How the harmony works

Enamel Blue Harmony Guide

Enamel Blue harmonies are computed from hue relationships rather than subjective palette names. Complementary colors create direct contrast, analogous colors stay close to the source hue, triadic and tetradic groups add broader palette range, split-complementary colors soften contrast, and monochromatic variants keep the same hue for UI surfaces and states.

Complementary Harmony1 colors · maximum hue contrast

Complementary harmony uses the color opposite the source hue. It creates the strongest direct relationship in the wheel, so it is best for accents, contrast anchors, and palettes that need immediate separation.

Behaviormaximum hue contrast

Best useaccent colors, strong calls to action, visual opposition

Source colorEnamel Blue · #0067A0

#9E3700#9E3700

Analogous Harmony2 colors · neighboring hue movement

Analogous harmony uses hues close to the source color. It keeps the palette visually connected and is useful for quiet interfaces, editorial color systems, and smooth background or gradient work.

Behaviorneighboring hue movement

Best usecalm palettes, gradients, natural transitions

#009E86#009E86

Triadic Harmony2 colors · three evenly spaced hues

Triadic harmony places colors around the wheel at equal intervals. It gives more range than analogous harmony while keeping a stable mathematical relationship between the selected hues.

Behaviorthree evenly spaced hues

Best usebalanced contrast, playful systems, broad palette range

#9E0067#9E0067

#679E00#679E00

Tetradic Harmony3 colors · two complementary pairs

Tetradic harmony creates a four-color system from two complementary relationships. It is useful when a palette needs multiple roles, but the colors should be assigned carefully so one hue remains dominant.

Behaviortwo complementary pairs

Best uselarge design systems, dashboards, multi-state UI

Split Complementary Harmony2 colors · softened complementary contrast

Split-complementary harmony replaces the direct opposite with the two hues beside it. This keeps useful contrast while reducing the visual tension of a pure complementary pair.

Behaviorsoftened complementary contrast

Best usebrand palettes, accent pairs, less aggressive contrast

Monochromatic Harmony3 colors · same hue, different values

Monochromatic harmony keeps the source hue and changes lightness. It is the safest system for tonal UI, cards, hover states, shadows, backgrounds, and subtle visual hierarchy.

Behaviorsame hue, different values

Best usesurfaces, states, elevation, restrained UI themes
