Abstract
A custom palette comprises colors on a plurality of luminance levels consisting of colors of uniform luminance. The spacing in luminance between levels varies in relation to the luminance, the spacing between levels being closer at low luminance and increasing at greater luminance. The palette preferably includes a gray color from each luminance level, highly saturated colors at the vertices of every alternate level, and a selection of lower saturation colors encircling the gray color on each level. The selection of lower saturation colors preferably includes a higher concentration of flesh and sky colors.
