CIE-Lab, XYZ and Yxy are measured against D65, the white point sRGB itself is defined against. Hunter Lab uses the original illuminant C constants, which is what paint and plastics specifications quote, so the two Lab rows are not directly comparable. CMYK is the plain arithmetic conversion: real ink values depend on the press, the paper and the profile.

Contrast and readability

Petrol on white measures 10.91:1 and on black 1.92:1. WCAG AA asks for 4.5:1 on normal text and 3:1 on large text and UI components, so the higher of those two decides which background it belongs on. In the scale above, 500 is the first to clear 4.5:1 on white, at 5.18:1.

The contrast checker reports every level for a given pair and suggests the nearest passing shade on the same hue. The color picker builds this same scale from any color you paste in.
