Caption text, which almost nothing passes.
WCAG 2.1
10.15:1
Passes AA for body text
AAA too. Swapping the two colours gives the same number — the ratio does not know which is the text.
APCA
Lc 80.3
Clears Lc 75 — body text at a normal size and weight.
Dark text on a lighter ground.
Colour difference
ΔE00 67.7
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 10.18:1, ΔE00 69.0.
deuteranopia
Ratio 10.14:1, ΔE00 67.1.
tritanopia
Ratio 9.66:1, ΔE00 66.8.
The weakest of the three is tritanopia, where the two are ΔE00 66.8 apart against 67.7 for a trichromat — still clearly two colours.
