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
4.36:1
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 39.2
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 50.1
different colours
Above 10 — related only in the sense that both are colours.
What the text colour has to become
#352803 is the nearest colour of the same hue that passes AA on #9488be, 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 4.38:1, ΔE00 51.4.
deuteranopia
Ratio 4.35:1, ΔE00 51.7.
tritanopia
Ratio 4.18:1, ΔE00 45.5.
The weakest of the three is tritanopia, where the two are ΔE00 45.5 apart against 50.1 for a trichromat — still clearly two colours.
