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
9.75:1
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 63.3
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 9.43:1, ΔE00 61.2.
deuteranopia
Ratio 9.92:1, ΔE00 64.0.
tritanopia
Ratio 10.13:1, ΔE00 68.9.
The weakest of the three is protanopia, where the two are ΔE00 61.2 apart against 63.3 for a trichromat — still clearly two colours.
