Using 2 complementary colors (i.e. orange and blue, yellow and purple, green and red) take one color in both directions on the color wheel (for example, orange, red orange and yellow orange) and do not mix the complement (blue) unless it's to make grays (mixed with oranges). You can use white sparingly. The example palettes show the possible color palettes, but not the neutrals. All kinds of yummy grays are possible!
