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 -39.1
Clears Lc 30 — the floor: below this the draft considers text not readable at any size.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 37.5
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #ae8a78 can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 4.56:1, ΔE00 36.9.
deuteranopia
Ratio 4.50:1, ΔE00 37.7.
tritanopia
Ratio 4.29:1, ΔE00 39.1.
The weakest of the three is protanopia, where the two are ΔE00 36.9 apart against 37.5 for a trichromat — still clearly two colours.
