About cyan-950

Tailwind cyan-950 is a vivid dark teal: OKLCH lightness 30.2%, chroma 0.056, hue 229.7 degrees. It closes the cyan scale as its darkest shade, 9.6 points of lightness below cyan-900.

HSL puts its lightness at 15% and OKLCH at 30.2%, 16 points apart: HSL's lightness does not follow what the eye sees, OKLCH's is built to. Its value fits inside sRGB, so #053345 is the same color, not an approximation.

White text on cyan-950 measures 13.41:1, past the 7:1 of WCAG AAA, while black text manages only 1.57:1. White text passes on every cyan shade from cyan-700 down, so cyan-950 is 3 shades past the line.

No CSS named color comes near it: the closest, darkslategray (#2f4f4f), is 0.107 away in OKLab.
