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
10.92:1
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 -82.5
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 73.2
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #cee1f2 can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 12.29:1, ΔE00 78.5.
deuteranopia
Ratio 10.29:1, ΔE00 69.4.
tritanopia
Ratio 9.42:1, ΔE00 73.4.
The weakest of the three is deuteranopia, where the two are ΔE00 69.4 apart against 73.2 for a trichromat — still clearly two colours.
