Limited palettes and gamut mapping

Choose a small base palette and keep every mixed color within a defined range on the color wheel.

What it is

A limited palette uses a small set of chosen base colors to mix the whole image. This might include warm and cool versions of each primary, a dark and a light, or one red, blue, yellow, and neutral.

Gamut mapping sets the allowed range of hues for a painting. You can mark this range mentally or on a color wheel, such as a blue-green-yellow section or a triangle between a warm red, cool blue, and gray. Every color stays within that range as you mix and adjust it.

You can test several palettes with scene thumbnails, keep allowed-color swatches beside the canvas, and adjust local colors to fit the chosen range. For example, a red object may shift toward orange in a blue-orange palette.

Why it matters

Palette limits help keep color relationships consistent across an image. Weak control can cause hues to drift, make mood harder to control, and make later palette changes risky.

You can check it when

• ✓List the base colors used in a finished piece and verify that they account for nearly all canvas colors.
• ✓Paint the same scene with separate warm and cool limited palettes, then compare whether each version maintains a unified color range.
• ✓Review the color wheel or picker history for a tight cluster or wedge of hues.
• ✓When adding a late color, compare it with the chosen gamut and record whether you adjusted it to fit or deliberately widened the range.
