Robin Egg Blue sits in the cyan / teal family, with the hex code #00CCCC mapping to rgb(0, 204, 204) in RGB and hsl(180, 100%, 40%) in HSL. In OKLCH it carries 77% perceptual lightness and 0.131 chroma — a moderately saturated, dark reading that behaves well as a primary, accent or decisive colour in modern interfaces. Cyan sits exactly where blue meets green and inherits the calm of both. It reads as clean, modern and slightly futuristic, which is why so many cloud, AI and medical brands gravitate to it — it feels technical without feeling cold.

Cyan washes out against bright backgrounds — it almost always needs at least 30% lightness reduction to clear AA on white. Watch saturation in dark mode too, where neon cyans bloom.
