Color Mixing Guide

Jump to Related Products


Throughout history, painters and authors have recommended various palettes of color. While some give insight to the painter’s working style, others offer a simple palette for mixing, but typically limit color possibilities. GOLDEN has created a palette of eight professional acrylic colors to provide you with the potential to mix the widest range of colors.


For this palette, the three mixing primaries are Benzimidazolone Yellow Medium, Quinacridone Magenta and Phthalo Blue (Green Shade). Our standard recommendation is Quinacridone Red, but we chose Quinacridone Magenta for mixing a broader range of violets and purples.

Naphthol Red Light helps balance the Quinacridone Magenta. Mixtures with Benzimidazolone Yellow Medium reveal a wider selection of intense reds and oranges. Mixtures with Phthalo Blue (Green Shade) allow deep reds and maroons.

Phthalo Green (Blue Shade) assists Phthalo Blue (Green Shade). Mixtures with Benzimidazolone Yellow Medium produce a great range of greens, particularly subtle yellow greens. This green is also useful for creating a diverse range of earth tones.

Yellow Ochre, a natural earth color, helps warm color mixtures and subdue the brightest colors.

Titanium White is an opaque white for creating light pastel tones. Zinc White is a very transparent white for subtle tinting and glazing.

Modern Color Mixing Guide


To describe color, we need to understand three qualities: Hue, Chroma and Value.

Hue is another word for color. It describes the actual color of something. Red, Green and Blue are hues. A cucumber and a lime are both hues of green.

Chroma is also referred to as saturation or intensity. It describes how brilliant or subdued the color looks. For example, within the hue of yellow, a lemon has more chroma than a banana.

Value refers to how dark or light a color is compared to white or black. Yellow is lighter in value, or closer to white, than dark blue. Sometimes it is difficult to determine the value of middle toned colors like orange and green. We easily understand value when we look at the range of Neutral Grays on the Virtual Color Guide. Try squinting while looking at colors to determine their value. Squinting helps the eyes' black and white receptors make value determinations, or make a gray scale to place next to the color in question.


Pigments are the particles in paint revealing hue. Every pigment is classified into two basic categories based on chemical composition - Organic pigments and Inorganic pigments.



Organic pigments are formed from complex carbon chemistry and are synthetically derived in laboratories.

Most organic pigments offer high chroma, high tinting strength and exceptional transparency. A transparent organic pigment, like a small piece of stained glass, allows light to pass through practically undisturbed. This characteristic allows mixtures with relatively high brilliance and clarity. Our mixing set includes five colors made from organic pigments: Benzimidazolone Yellow Medium, Quinacridone Magenta, Phthalo Blue (Green Shade), Phthalo Green (Blue Shade) and Naphthol Red Light.


Inorganic pigments are not based on carbon chemistry, but instead are derived from natural minerals or ores. These materials are oxides, sulfides, or various slats of metallic elements. Examples include iron oxide, cadmium sulfides and titanium dioxides.

Most inorganic pigments offer relatively low chroma, low tinting strength and a moderate to high degree of opacity. (Zinc White is the exception.) Using inorganics for blending color yields mixtures with low chroma, but excellent opacity. Our mixing set includes three colors made from inorganic pigments: Titanium White, Zinc White and Yellow Ochre.


In order to more fully understand how to mix acrylic color we need to define other important attributes of paint color including: Masstone, Undertone and Tinting Strength.


The masstone, or main paint color, is paint applied so it completely covers the surface and underlying colors cannot show through. For example, when Phthalo Blue is thickly applied, the masstone appears near black.


The undertone of a color is visible when we spread the color very thinly over a white surface. This can be done by scraping the color over a surface or by thinning the colors dramatically with acrylic medium or water. Certain colors, such as the Cadmiums and Cobalts, have similar masstones and undertones. With the transparent organic colors like the Quinacridones or Phthalos, the undertone can be quite different from what might be expected by looking at the masstone. These shifts in hue positions provide some of the incredible richness and magic to working with color.

Undertone is important when using acrylic in a watercolor style, as the brilliance of watercolor comes from the white paper transmitting through the transparent layers of color.

Tinting Strength

Tinting strength is the ability of a color to change the character of another color. We determine this by adding the same amount of Titanium White to each color and observing the resulting strength of the color mixture. Weak tinting colors create light pastel mixtures. Stronger tinting colors create more saturated blends.


Color Wheel

The color wheel provides structure to the discussion of color and gives a reference point that allows us to draw useful conclusions about how colors interact. Start with Blue, Red and Green. In the natural world, these colors exist along the electromagnetic spectrum in a straight line, by plotting these primaries on an equilateral triangle we find great insight into color mixing. We similarly plot the subtractive primaries: Cyan, Magenta and Yellow.

Natural white light contains all colors. When light meets a surface, its energy is either absorbed, reflected or bent. A surface painted Black absorbs almost all the light energy that hits the surface. A surface painted White reflects all the light energy back from the surface. A surface painted Yellow absorbs Blue and reflects the Red and Green within the white light. Colors absorb certain wavelengths of energy and reflect other light energies.

Unfortunately, manufacturers do not create perfect primary Blue, Red or Green. Nor do they create pure Magenta, Cyan or Yellow. When first learning about color relationships we refer to a color wheel that aligns color so that we can understand color theory, and we use practical experience to truly understand how actual paints mix with one another.


Artists are familiar with color wheels showing Red, Yellow and Blue as primaries and Purple, Orange and Green as the secondaries. Secondaries result from the mixture of two primaries, i.e. Red and Yellow make Orange. However, which Red, Yellow and Blue selected can dramatically change the secondary mixture.

A set of classic Inorganic primary colors are Cadmium Red Light, Cadmium Yellow Medium and Ultramarine Blue. These colors, although beautiful in their own right, severely limit color mixing possibilities. The resulting mixtures have lower values and chromas than mixtures with organic primary colors such as Naphthol Red Light, Benzimidazolone Yellow Medium and Phthalo Blue Green Shade.


Complementary Color Wheel

We filled the color wheel with our color names to develop an understanding of mixing possibilities. Mixing from opposite sides of the color wheel will yield black or gray. This is called mixing complements. For example, we see that Phthalo Green and Naphthol Red Light are almost directly opposite one another. The mixing of these two will yield a simple black. For this reason, the mixing set does not include black.

Adding a color's complement reduces the chroma of the mixture. For example, mixing a small amount of Phthalo Green into Naphthol Red Light reduces its intensity, however, it also changes the value of the color. To avoid reducing the value of the mixture, use the Neutral Gray of the same value as the color you are trying to mix, or mix a gray from the black produced with your green and red mixture with Zinc or Titanium White.

Relative Tinting Strength of Colors


Before we explore the blending possibilities and color relationships, we need to describe the colors in the mixing set. The pigment loads are not balanced as with "student grade" colors. With professional "artist grade" colors, the high tinting colors are much more powerful than lower tinting colors. The highest tinting colors are Phthalo Blue and Phthalo Green. Next are Naphthol Red Light and Quinacridone Magenta. Benzimidazolone Yellow Medium has very little tinting strength.


To mix the colors, use the table as a guide. For example, to mix Turquoise, mix equal parts of Phthalo Blue and Phthalo Green. To mix Bright Green, mix one part Phthalo Green with nine parts Benzimidazolone Yellow Medium.

Tint Strength of Benzimidazolone Yellow Medium: In order to balance the much stronger tint strength of Phthalo pigment, it is important to add much smaller amounts of them compared to much higher amounts of this yellow.


If you have ever been to a paint store and had color mixed, you have seen the results from adding white to pure color. Each house paint color, in order to be cover well, is mixed with white. Most brands produce three different mixing whites; one very strong white for pastel hues, one middle strength white for middle color values and one fairly weak white for deeper tones of color.

Adding Titanium White to any of your colors increases coverage. This is especially true for the more transparent colors. It is also a general rule that the lighter the original value of a color, the less dramatic the value shift when you add Titanium White. Adding Zinc White to transparent colors will not dramatically increase your opacity. It can be used to create subtle, tinted glazes. Keep in mind mixtures with Zinc White will not provide good coverage.

If you choose to increase opacity, but do not want to change your color value, then use gray of the same color value. As before, this will reduce your chroma, but will allow you to maintain your balance of light to dark while increasing your opacity.


A good deal of painting requires the use of the earth color palette. With high chroma colors, it seems almost impossible to mix colors like Burnt Sienna, Red Oxide or Raw Umber.

Mixing medium greens through lime greens with orange-reds through orange-yellows offers an incredible array of earth colors. When you mix organic pigments, you maintain excellent clarity of color.


The color blends achievable with the five mixing primaries, plus the two whites, is enormous. Yet, you may need to reduce the intensity of the color for a more subtle quality. Yellow Ochre offers a warming of colors with a subdued glow. Used with Titanium White to tint colors, Yellow Ochre furnishes an opaque alternative to the bright white used to create the pastel range. Used with Zinc White, Yellow Ochre is transparent enough to create a glazing mixture, or deeper warmer tones within the more brilliant colors. Some artists suggest using Yellow Ochre instead of Benzimidazolone Yellow Medium to create a different palette of colors.


A glass palette offers a great surface for working with acrylic colors. Its smooth, nonporous surface makes mixing colors quite easy.

Acrylics dry by the process of evaporation. As the water releases from the paint, the acrylic polymer spheres come in greater contact with one another and eventually fuse to form a continuous film. To extend the working time of acrylic, you can add GOLDEN Retarder to the paint. GOLDEN Acrylic Glazing Liquid can be added to create glazes and keep the paint wet longer. To keep your palette fresh, we recommend lightly misting the colors on the palette with water every few minutes. A plant mister works well.

The acrylic used with all professional artist colors is an emulsion product. It is created by chaining together hundreds of thousands of acrylic molecules (monomers) within a water base. The process to make acrylic compatible with water requires a surfactant. A surfactant acts like a bridge allowing water and acrylic to work together.

This procedure of mixing acrylic with water creates a milky emulsion. While you are working with the paint, the acrylic emulsion is quite white. The wet emulsion "tints" the color; however, when the water evaporates, the acrylic shows its exceptional clarity. This causes a large shift in value in very transparent colors such as Phthalo Blue. The shift in value is not noticeable in colors with light values such as Benzimidazolone Yellow Medium so, be aware of the possible shifts in value of acrylic colors. It can be disappointing to mix a color exactly the way you want, and to have it dry to a much deeper color. It is helpful to lay down a little of your transparent color and let it dry to see if it is still the color you desire. Another way to compensate for this value shift is to add a small amount of Zinc White to the color.

To achieve glazes (very thin, transparent films), add Gloss Medium to the color. To reduce gloss, add Matte Medium.

GOLDEN produces nearly 40 Gel and Mediums, creating a tremendous range of textures, finishes and working properties for acrylic paint. Because of their unusual strength, most colors can be diluted substantially with gels or mediums and retain much of their color strength.

Acrylics clean with soap and water. Keep tools wet to assist cleaning. If paints dry on the palette, simply run a wet sponge over the surface and wait about one minute. The acrylic will easily peel off. Avoid getting paint on clothing. It will hold quite well!


At Golden Artist Colors, we are involved in exploring new technologies for the professional artist. This has inevitably led us to many of the newly developed pigments that have been made available to artists during the 21st century. Some, like YInMn Blue, have only been around for several years.

We are very proud to have been the first to provide the professional artist with many unique and lightfast pigments, including Quinacridones, Phthalos, Bismuth Yellow, Nickel Azos, Interference Colors and more.

Additionally, through our formulating advancements we have been able to stabilize Zinc White, which previously had not been available in acrylic paint. We have also provided a near perfect match for the fugitive but beautiful Alizarin Crimson with our mixture of Quinacridone Crimson. The entire family of Interference Colors was also introduced for the first time to artists by our company.

Acrylics continue to be the fastest growing segment of the fine art market. Through our custom work with artists, museums and conservators all over the world, we have assembled a formidable range of color choices, and continue to work to develop new and unique colors for our customers.

Identifying the various qualities of color

Step 1: Locate Quinacridone Magenta, Phthalo Blue (Green Shade) and Benzimidazolone Yellow Medium on the GOLDEN Master Color Chart. These colors are the mixing primaries for this guide.

Step 2: Find C.P. Cadmium Red Dark and Red Oxide. Observe the difference between the colors" chroma. The Cadmium Red has a much greater chroma, or saturation, than Red Oxide.

Step 3: Locate the colors Yellow Ochre and Naples Yellow Hue. Both have nearly the same hue and chroma, yet the Naples Yellow Hue is much lighter in value than the Yellow Ochre. Find the Neutral Grays on the bottom of the color chart, and try to match the value appropriate Neutral Gray for both of these colors.

Understanding the difference between Titanium White and Zinc White

Step 1: With a palette knife, apply a thick, opaque stroke of each color to show its masstone. Turn the knife on its edge and scrape the color to show its undertone.

Step 2: Apply some Titanium White to a card and mix a color so that the resulting mixture is graduated from a very light tint to its original hue.

Step 3: Repeat the same mixtures using Zinc White. It is helpful to label your examples and take notes for future reference.

Using the mixing primaries

Before exploring all the mixing possibilities, first investigate mixing using the primary colors, Phthalo Blue (Green Shade), Quinacridone Magenta and Benzimidazolone Yellow Medium. To create colors along the wheel between these primaries use the following tinting ratios.

Turquois - 1 part Phthalo Blue G/S / 1 part Phthalo Green B/S
Light Red - 1 part Quinacridone Magenta / 5 parts Benzimidazolone Yellow Medium
Permanent Green Light - 1 part Phthalo Blue G/S / 10 parts Benzimidazolone Yellow Medium

Mixing a full range of Earth colors with organic pigments

Step 1: Mix 10 parts Benzimidazolone Yellow Medium with 1 part Phthalo Green (Blue Shade) to create a bright green color. Lightly spray with water and set aside.

Step 2: Mix 5 parts Benzimidazolone Yellow Medium with 1 part Quinacridone Magenta to create a bright red color.

Step 3: Take a small, equal amount from each mixture and blend together. Record the results by brushing it on a white board.

Step 4: Mix 2 parts of the bright green with 1 part of the bright red. Record results.

Step 5: Mix 4 parts of the bright green with 1 part of the bright red. Record results.

Step 6: Try the same mixtures as above but first mix a bright, lime green using mostly Benzimidazolone Yellow Medium and a very small amount of Phthalo Green B/S. Record this green as it is a major mixing color for producing a variety of unique colors from Green Gold hue through Nickel Azo Yellow hue and Quinacridone Gold hue.

Mixing to achieve black and gray using Phthalo Blue G/S, Quinacridone Magenta, and Benzimidazolone Yellow Medium

Step 1: Mix 1 part of Phthalo Blue (Green Shade) with 2 parts Quinacridone Magenta. The mixture will be correct when you perceive it to be the deepest blue without being described as purple. This is an approximate primary blue.

Step 2: Mix 2 parts primary blue with 1 part Benzimidazolone Yellow Medium.

Step 3: Tint a small portion of the resulting color with Titanium White.

Mixing to achieve black and gray using Phthalo Blue B/S, and Naphthol Red Light

Step 1: Mix 1 part Phthalo Green (Blue Shade) with 2 parts Naphthol Red Light.

Step 2: Tint a small portion of the resulting color with Titanium White.

Mixing to achieve black and gray using Quinacridone Magenta, Benzimidazolone Yellow Medium, and Phthalo Green B/S

Step 1: Mix Quinacridone Magenta with a small amount of Benzimidazolone Yellow Medium. The resulting mixture should look like a bright Quinacridone Crimson hue. (See Virtual Color Guide)

Step 2: Mix 1 part Phthalo Green (Blue Shade) with 2 parts of the above crimson hue.

Step 3: Tint a small portion of the resulting color with Titanium White.

Label all your cards for future reference.
