Lagoon sits in the cyan / teal family, with the hex code #4D8C8C mapping to rgb(77, 140, 140) in RGB and hsl(180, 29%, 42.5%) in HSL. In OKLCH it carries 60% perceptual lightness and 0.065 chroma — a desaturated, 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.
