Atomic Pink on Castro
#fb7efd on #44232f
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
6.22:1
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 -54.6
Clears Lc 45 — large or heavy display text.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 53.9
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #fb7efd can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 5.47:1, ΔE00 47.7.
deuteranopia
Ratio 6.59:1, ΔE00 57.2.
tritanopia
Ratio 6.99:1, ΔE00 58.6.
The weakest of the three is protanopia, where the two are ΔE00 47.7 apart against 53.9 for a trichromat — still clearly two colours.
