Contrast and readability

Slate on white measures 7.61:1 and on black 2.76:1. 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 5.28:1.

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.
