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.

Large text only
Not AAA (7:1). Swapping the two colours gives the same number — the ratio does not know which is the text.

Above 10 — related only in the sense that both are colours.
What the text colour has to become
#a84659 is the nearest colour of the same hue that passes AA on #00ffee, 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 6.00:1, ΔE00 45.4.
deuteranopia
Ratio 3.61:1, ΔE00 39.1.
tritanopia
Ratio 2.19:1, ΔE00 55.5.
The weakest of the three is deuteranopia, where the two are ΔE00 39.1 apart against 73.3 for a trichromat — still clearly two colours.
