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
1.26:1
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 -12.0
Below Lc 15: the draft treats this as not text.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 47.8
different colours
Above 10 — related only in the sense that both are colours.
What the text colour has to become
#584070 is the nearest colour of the same hue that passes AA on #b8bf71, 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 1.22:1, ΔE00 44.1.
deuteranopia
Ratio 1.29:1, ΔE00 42.5.
tritanopia
Ratio 1.28:1, ΔE00 6.5.
The weakest of the three is tritanopia, where the two are ΔE00 6.5 apart against 47.8 for a trichromat — still two colours, but a closer call than it looks to you.
