Triadic Color Palettes: Creating Harmony with Three Colors
Updated: Sep 23
With so many colors available, choosing a palette can sometimes feel more complicated than it needs to be.
One of my favorite ways to simplify color is to begin with a limited palette. Using fewer colors helps me think more carefully about relationships, mixtures, and harmony instead of reaching for a different pigment every time I need a new color.
One especially useful approach is a triadic color palette—three colors that are spaced approximately evenly around the color wheel.

What Is a Triadic Color Palette?
A triadic palette begins with three colors positioned roughly equal distances apart on the color wheel.
Once I choose those three colors, I try to mix the rest of the painting from them rather than continually adding new pigments. That limitation can produce a surprisingly wide range of color while helping the entire painting feel connected.
Because each mixture shares one or more of the same parent colors, even very different passages tend to relate naturally to one another.

Why Limited Color Creates Harmony
What I love about a triadic palette is the harmony it creates almost automatically.
Since every mixture comes from the same three colors, those colors quietly repeat throughout the painting. A green may contain the same blue and yellow that appear elsewhere; a neutral may contain traces of all three colors.
The result can be a wide variety of mixtures without the painting feeling disconnected or overly colorful.
Limiting the palette doesn’t necessarily limit the painting. In many cases, it gives me more freedom because I can concentrate on value, temperature, edges, and expression rather than constantly deciding which pigment to use.

There Is More Than One Triad
A triadic palette isn’t limited to one particular set of three colors. You can choose different triads depending on the mood and dominant color you want in the painting.
Some combinations will feel warmer, cooler, brighter, or more subdued than others. Experimenting with different triads is a wonderful way to discover color relationships you might not have considered otherwise.

A Working Triadic Palette
For this palette, I used New Gamboge, Alizarin Crimson, and Peacock Blue. The additional colors you see in the wells were mixed from those three pigments.
Seeing the mixtures together like this is a good reminder of just how much variety can come from a very limited starting palette.

If you’ve never tried painting with only three colors, give it a try. Make a few small mixtures first and see how many greens, neutrals, violets, oranges, and other variations you can create before beginning the painting.
Limiting your choices can feel restrictive at first, but it often leads to greater color harmony—and sometimes to mixtures you never would have discovered otherwise.
