How do you make brown using complementary colors in acrylic paint?

March 5, 2026 · caitlin

To make brown using complementary colors in acrylic paint, you’ll mix two colors that are opposite each other on the color wheel. Typically, this involves mixing a primary color with the secondary color directly opposite it. For instance, mixing blue and orange, red and green, or yellow and violet will produce various shades of brown.

Understanding Complementary Colors for Brown in Acrylics

The magic of creating brown with acrylics lies in understanding the color wheel and the principle of complementary colors. When you mix two complementary colors, they neutralize each other, resulting in a muted tone. This muted tone, especially when dealing with a primary and its opposite secondary color, often lands squarely in the brown spectrum.

What Are Complementary Colors?

Complementary colors are pairs of colors that, when combined or mixed, cancel each other out (lose hue) by producing a grayscale color like white or black. On a standard artist’s color wheel, these pairs sit directly opposite each other.

Red and Green
Blue and Orange
Yellow and Violet (Purple)

Why Do They Create Brown?

When you mix these opposing colors, you’re essentially combining all the primary colors in a specific ratio. For example, orange is made from red and yellow. When you mix blue with orange (red + yellow), you’re mixing blue + red + yellow. This combination of all three primaries, in the right proportions, is what forms brown.

Practical Methods for Mixing Brown with Complementary Colors

The specific shade of brown you achieve will depend on the exact hues of the complementary colors you choose and their proportions. Experimentation is key to mastering this technique.

Method 1: Blue and Orange

This is a very common and effective way to create a rich brown.

Base: Start with a medium blue (like Ultramarine Blue or Cobalt Blue).
Complement: Add orange. A burnt orange or a standard orange will work well.
Ratio: Begin with more blue and gradually add small amounts of orange. Too much orange can make the brown lean too red or too muddy.
Result: This combination typically yields a warm, reddish-brown or a deeper, chocolate brown.

Method 2: Red and Green

This pairing can produce a variety of browns, from earthy tones to darker, more subdued shades.

Base: Use a true red (like Cadmium Red Medium) or a slightly cooler red.
Complement: Mix with green. A forest green or an olive green will give different results.
Ratio: Similar to the blue and orange method, start with the primary color (red) and slowly introduce the green.
Result: This often creates a more earthy, olive-toned brown.

Method 3: Yellow and Violet

This combination can be a bit trickier but can produce beautiful, unique browns.

Base: A bright yellow (like Cadmium Yellow Light).
Complement: Add violet (purple). A medium violet or a reddish-violet will yield different results.
Ratio: Start with the yellow and add small amounts of violet.
Result: This can create a warm, golden brown or a cooler, more muted brown depending on the specific shades used.

Adjusting Your Brown: Fine-Tuning the Shade

Once you’ve mixed your initial brown, you can adjust its tone and value.

Making it Lighter (Tints)

To lighten any brown you’ve created, add white. Start with small amounts of white and mix thoroughly. Adding too much white too quickly can make your brown look chalky or pastel.

Making it Darker (Shades)

To deepen your brown, you can add a touch of its complementary color’s darker counterpart. For instance, if you made brown from blue and orange, adding a tiny bit of black or a very dark blue can deepen it. Alternatively, you can add a small amount of black or a dark earth tone like Burnt Umber.

Adjusting the Hue

Warmer Brown: Add a touch of red or yellow.
Cooler Brown: Add a touch of blue.
More Earthy: Add a touch more of the green or violet component.

Tips for Success When Mixing Brown

Achieving the perfect brown requires patience and practice. Here are some helpful tips.

Use High-Quality Paints: Artist-grade acrylics often have more pigment concentration, leading to richer and more vibrant mixes.
Work in Small Batches: It’s easier to add more paint to a small amount than to fix a large batch that’s gone wrong.
Keep Notes: Record the specific paints and ratios you used to recreate a particular brown. This is invaluable for future projects.
Consider the Undertones: Think about whether you want a warm brown (more red/yellow) or a cool brown (more blue/green). This will guide your initial color choices.
Test Swatches: Always paint a small swatch on scrap paper or canvas to see the true color once it dries. Acrylics can dry slightly darker than they appear when wet.

Example Scenario: Creating a Chocolate Brown

Let’s say you want to paint a wooden table and need a rich chocolate brown.

Start with Ultramarine Blue.
Add Burnt Orange. Begin with a ratio of about 4 parts blue to 1 part orange.
Mix thoroughly. Observe the color. It might be a muted, dark purple-brown.
Adjust: Add a tiny bit more orange to warm it up, or a touch more blue if it’s too reddish.
Fine-tune: If it’s too dark, add a small amount of white. If it needs more depth, a minuscule touch of black can be added, but be very careful not to overdo it.
