Neon Boneyard on Nougat

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
2.02:1
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 -33.7
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 31.0
different colours
Above 10 — related only in the sense that both are colours.
What the text colour has to become
#38214e is the nearest colour of the same hue that passes AA on #ae8a78, 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 2.08:1, ΔE00 35.4.
deuteranopia
Ratio 1.99:1, ΔE00 36.3.
tritanopia
Ratio 1.88:1, ΔE00 23.3.
The weakest of the three is tritanopia, where the two are ΔE00 23.3 apart against 31.0 for a trichromat — still clearly two colours.
