Under colour blindness
Contrast is a lightness relationship, so a ratio survives colour blindness — but the pair can still lose the distinction it was carrying. This is the same two colours as seen with each dichromacy.

What the thresholds mean
- 4.5:1 — WCAG 2.2 success criterion 1.4.3, the minimum for body text.
- 3:1 — the minimum for large text (18.66 px bold or 24 px regular) and, under 1.4.11, for any non-text thing you have to perceive: input borders, icons, focus indicators.
- 7:1 — AAA, criterion 1.4.6.
- APCA Lc 30 — a perceptual model that accounts for polarity, so dark-on-light and light-on-dark are not treated as the same problem. It is the direction WCAG 3 is heading and it disagrees with the ratio often enough to be worth reading alongside it.
