#FAQ
How does color mixing work? ▾
Color mixing averages the RGB channels of two colors. You can adjust the mix ratio to weight one color more heavily. A 50/50 mix of #FF0000 and #0000FF produces #800080 (purple).
How is a complementary color calculated? ▾
The complement of a color is found by subtracting each RGB channel from 255. For example, the complement of #3366CC is #CC9933.
