How to choose duotone colors
Duotone works by reading image brightness and mapping dark areas to one color and light areas to another. Use a dark shadow color and a bright highlight color for stronger contrast.
For brand graphics, use a deep neutral or brand dark color for shadows and a bright accent color for highlights.
