摘要： 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.

摘要翻译： 自定义调色板包括由均匀亮度的颜色组成的多个亮度级的颜色。 亮度之间的亮度间隔相对于亮度而变化，在低亮度下电平之间的间隔更接近并以更高亮度增加。 调色板优选地包括来自每个亮度级的灰色，每个交替水平的顶点处的高度饱和的颜色，以及在每个级别上包围灰色的较低饱和度颜色的选择。 较低饱和度颜色的选择优选地包括更高浓度的肉和天空颜色。
