Tetradic colors
Colors positioned on the color wheel along a rectangle or square. One of Johannes Itten's "harmonious chords": geometric points demonstrating color "notes" as a basis for composition.

How it affects UI design
Tetradic colors provide a wide range of differentiation of color in a UI color palette.
A tetradic palette may be prone to color conflicts for people who have a color vision deficiency.
Hue is treated differently between color spaces, which can affect which colors are considered to be tetradic.
