Color Scheme 6
A rectangle of colors (double complementary).
A tetradic color scheme, an outstanding variant of the twin color scheme, with an equal distance between all colors. All four colors are divided evenly around the color wheel, resulting in there being no clear dominance of one color.
The tetradic (double complementary) scheme is the richest of all the schemes because it uses four colors organized into two complementary color pairs.
Tetrad is a very aggressive color scheme, needing very good planning and very emotional approach to relations of these colors.
The scheme is always vibrant, scared and colorful, there is equal tension between all colors.
This rich color scheme offers plenty of likelihoods for variation. The tetradic color scheme works best if you let one color be dominant.
You should also pay attention to the balance between warm and cool colors in your design.
This scheme is hard to harmonize; if all four colors are used in equal amounts, the scheme may look unbalanced, so you should choose a color to be dominant or overwhelm the colors.
