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
4.09:1
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 -47.9
Clears Lc 45 — large or heavy display 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
#f0abb7 is the nearest colour of the same hue that passes AA on #494e4f, 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 3.68:1, ΔE00 37.0.
deuteranopia
Ratio 4.32:1, ΔE00 41.7.
tritanopia
Ratio 4.72:1, ΔE00 58.8.
The weakest of the three is protanopia, where the two are ΔE00 37.0 apart against 45.2 for a trichromat — still clearly two colours.
