Body text at this size
And the smaller size most interfaces actually use for paragraphs — the size that decides whether a pair is usable.
Caption text, which almost nothing passes.
WCAG 2.1
3.99:1
Large text only
Not AAA (7:1). Swapping the two colours gives the same number — the ratio does not know which is the text.
APCA
Lc 56.4
Clears Lc 45 — large or heavy display text.
Dark text on a lighter ground.
Colour difference

different colours
Above 10 — related only in the sense that both are colours.
What the text colour has to become
#a34154 is the nearest colour of the same hue that passes AA on #f2d6da, at 4.50:1. Only the lightness moved — which is the point: your colour stays recognisably your colour.
And to someone missing a cone
protanopia
Ratio 4.80:1, ΔE00 40.6.
deuteranopia
Ratio 3.68:1, ΔE00 33.7.
tritanopia
Ratio 2.87:1, ΔE00 26.4.
The weakest of the three is tritanopia, where the two are ΔE00 26.4 apart against 38.0 for a trichromat — still clearly two colours.
