Vermilion Color Harmonies
Vermilion harmonies from #E34234: complementary #35D5E3, plus five harmony groups with CSS and contrast data.
Vermilion is a warm red at hue 5°, saturation 76% and lightness 55%. The sets below keep those measurements visible while moving around the color wheel, making it easier to choose close hues, direct contrast or a wider token system.
How the harmony works
Vermilion Harmony Guide
Vermilion 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.
