Caption text, which almost nothing passes.
WCAG 2.1
6.92:1
Passes AA for body text
Not AAA (7:1). Swapping the two colours gives the same number — the ratio does not know which is the text.
APCA
Lc 59.5
Clears Lc 45 — large or heavy display text.
Dark text on a lighter ground.
Colour difference
ΔE00 55.6
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #3e2723 can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 7.16:1, ΔE00 54.9.
deuteranopia
Ratio 6.80:1, ΔE00 54.2.
tritanopia
Ratio 6.45:1, ΔE00 53.5.
The weakest of the three is tritanopia, where the two are ΔE00 53.5 apart against 55.6 for a trichromat — still clearly two colours.
