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
4.06:1
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

Clears Lc 60 — headlines and other larger text.
Light text on a darker ground — the negative sign is the polarity.
Colour difference

different colours
Above 10 — related only in the sense that both are colours.
What the text colour has to become
#d9ecfd is the nearest colour of the same hue that passes AA on #ac495c, 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 5.13:1, ΔE00 42.6.
deuteranopia
Ratio 3.64:1, ΔE00 39.4.
tritanopia
Ratio 2.81:1, ΔE00 50.8.
The weakest of the three is deuteranopia, where the two are ΔE00 39.4 apart against 48.3 for a trichromat — still clearly two colours.
