Heavy Cream on Flirt
#e8ddc6 on #7a2e4d
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
6.70:1
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 -73.3
Clears Lc 60 — headlines and other larger text.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 57.7
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #e8ddc6 can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 7.85:1, ΔE00 60.4.
deuteranopia
Ratio 6.23:1, ΔE00 49.1.
tritanopia
Ratio 5.15:1, ΔE00 42.3.
The weakest of the three is tritanopia, where the two are ΔE00 42.3 apart against 57.7 for a trichromat — still clearly two colours.
