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
6.48:1
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 48.4
Clears Lc 45 — large or heavy display text.
Dark text on a lighter ground.
Colour difference
ΔE00 56.8
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #0c121b can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 7.18:1, ΔE00 59.4.
deuteranopia
Ratio 6.11:1, ΔE00 53.8.
tritanopia
Ratio 6.04:1, ΔE00 46.8.
The weakest of the three is tritanopia, where the two are ΔE00 46.8 apart against 56.8 for a trichromat — still clearly two colours.
