Caption text, which almost nothing passes.
WCAG 2.1
9.48:1
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 -62.6
Clears Lc 60 — headlines and other larger text.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 64.5
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #d9ae86 can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 8.89:1, ΔE00 59.2.
deuteranopia
Ratio 9.79:1, ΔE00 63.6.
tritanopia
Ratio 10.39:1, ΔE00 74.5.
The weakest of the three is protanopia, where the two are ΔE00 59.2 apart against 64.5 for a trichromat — still clearly two colours.
