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
1.22:1
Fails AA
Not AAA (7:1). Swapping the two colours gives the same number — the ratio does not know which is the text.
APCA
Lc 10.2
Below Lc 15: the draft treats this as not text.
Dark text on a lighter ground.

different colours
Above 10 — related only in the sense that both are colours.
What the text colour has to become
#745c8f 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 1.42:1, ΔE00 22.4.
deuteranopia
Ratio 1.12:1, ΔE00 8.2.
tritanopia
Ratio 1.15:1, ΔE00 35.9.
The weakest of the three is deuteranopia, where the two are ΔE00 8.2 apart against 39.7 for a trichromat — still two colours, but a closer call than it looks to you.
