Coral (#FF7F50) is a light, highly saturated orange hue. Coral blends orange and pink and was a recent colour-of-the-year favourite for lifestyle brands.
In RGB it is made of 255 red, 127 green and 80 blue. Its HSL hue angle is 16° with 100% saturation and 66% lightness, while its perceptual OKLCH lightness is 74% with a chroma of 0.168. For print, a starting CMYK mix is 0% cyan, 50% magenta, 69% yellow and 0% black.
As a text color on white, Coral has a contrast ratio of 2.5:1, which fails WCAG AA even for large text. On black it reaches 8.4:1 and passes AA for normal text. If you use Coral as a background, put black (or very dark) text on it. The APCA lightness contrast is Lc 56 for black text and Lc -54 for white text.
Its perceptual complement is #00BCE3, close to process cyan. Colors that look most similar are salmon, tangerine, terracotta. People with red-green color blindness see coral quite differently (ΔE 15), so do not rely on it alone to signal meaning.
