Hue is the angular position of a color in the circle, usually from 0 to 359 degrees in HSL.
Color Wheel
Build analogous, complementary, triadic, tetradic and monochrome harmonies with controllable HSL.
The color wheel organizes perceptual relationships
The color wheel helps choose coherent palettes: analogous colors are close and calm, complementary colors create contrast, triadic palettes distribute energy and monochrome schemes vary without changing hue. In interfaces, color choice must consider contrast, function, state and visual culture, not just aesthetics.
Choose a base color and tune the intent
- Set the base hue in degrees, then adjust saturation and lightness.
- Choose the harmony scheme according to the palette's role.
- Copy the HEX values and validate contrast in the real interface context.
