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
14.39:1
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 -85.6
Clears Lc 75 — body text at a normal size and weight.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 88.8
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #e8ddc6 can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 14.22:1, ΔE00 89.1.
deuteranopia
Ratio 14.48:1, ΔE00 90.4.
tritanopia
Ratio 14.43:1, ΔE00 97.0.
The weakest of the three is protanopia, where the two are ΔE00 89.1 apart against 88.8 for a trichromat — still clearly two colours.
