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
4.91:1
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 41.9
Clears Lc 30 — the floor: below this the draft considers text not readable at any size.
Dark text on a lighter ground.
Colour difference
ΔE00 47.6
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #0f282f can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 4.53:1, ΔE00 40.3.
deuteranopia
Ratio 5.13:1, ΔE00 46.0.
tritanopia
Ratio 5.36:1, ΔE00 68.5.
The weakest of the three is protanopia, where the two are ΔE00 40.3 apart against 47.6 for a trichromat — still clearly two colours.
