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
1.15:1
Fails AA
Not AAA (7:1). Swapping the two colours gives the same number — the ratio does not know which is the text.
APCA
Lc 0.0
Below Lc 15: the draft treats this as not text.
Too close to call.
Colour difference
ΔE00 29.9
different colours
Above 10 — related only in the sense that both are colours.
What the text colour has to become
#625845 is the nearest colour of the same hue that passes AA on #dfc5fe, 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 1.17:1, ΔE00 30.7.
deuteranopia
Ratio 1.14:1, ΔE00 30.3.
tritanopia
Ratio 1.15:1, ΔE00 10.3.
The weakest of the three is tritanopia, where the two are ΔE00 10.3 apart against 29.9 for a trichromat — still clearly two colours.
