Flirt on Ghost Writer
#7a2e4d on #bcb7ad
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
4.52:1
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 49.3
Clears Lc 45 — large or heavy display text.
Dark text on a lighter ground.
Colour difference
ΔE00 49.4
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #7a2e4d can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 5.32:1, ΔE00 50.5.
deuteranopia
Ratio 4.19:1, ΔE00 40.2.
tritanopia
Ratio 3.47:1, ΔE00 35.8.
The weakest of the three is tritanopia, where the two are ΔE00 35.8 apart against 49.4 for a trichromat — still clearly two colours.
