Screenshots - Color schemes
Create color schemes by tapping the Color Scheme icon. The five scheme options are Monochromatic, Analogous, Triadic, Complementary, and Split Complementary. Like the blend screen you drag an existing color to one of the start chips.
Once one of the start chips is set all the other colors are calculated. The first column is the scheme based on the set color. All the other columns are variations of the first column by setting different levels of saturation and brightness.
