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
3.81:1
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 -36.4
Clears Lc 30 — the floor: below this the draft considers text not readable at any size.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 43.4
different colours
Above 10 — related only in the sense that both are colours.
What the text colour has to become
#ff4ab2 is the nearest colour of the same hue that passes AA on #322c2b, at 4.50:1. Only the lightness moved, and some chroma was given up to stay inside sRGB — which is the point: your colour stays recognisably your colour.
And to someone missing a cone
protanopia
Ratio 2.42:1, ΔE00 30.9.
deuteranopia
Ratio 4.54:1, ΔE00 39.2.
tritanopia
Ratio 6.62:1, ΔE00 55.7.
The weakest of the three is protanopia, where the two are ΔE00 30.9 apart against 43.4 for a trichromat — still clearly two colours.
