How to choose the best color scheme for your design?
If your design uses 4 colors, one rule of thumb is to assign 1/3 of the design space to one color, making it the dominant, and then break up the remaining two-thirds of the design into smaller, unequal areas: 1/3:1/6:1/6. The color that is used least can become the accent if it is lighter or darker enough in relation to the other colors.
How to create interest with 3 color schemes?
