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
4.22:1
Large text only
Not AAA (7:1). Swapping the two colours gives the same number — the ratio does not know which is the text.
APCA
Lc -48.5
Clears Lc 45 — large or heavy display text.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 41.2
different colours
Above 10 — related only in the sense that both are colours.
What the text colour has to become
#eda8b4 is the nearest colour of the same hue that passes AA on #654243, at 4.50:1. Only the lightness moved — which is the point: your colour stays recognisably your colour.
And to someone missing a cone
protanopia
Ratio 4.10:1, ΔE00 40.4.
deuteranopia
Ratio 4.27:1, ΔE00 40.5.
tritanopia
Ratio 4.33:1, ΔE00 41.0.
The weakest of the three is protanopia, where the two are ΔE00 40.4 apart against 41.2 for a trichromat — still clearly two colours.
