Heavy Cream on Sprinkled With Pink
#e8ddc6 on #e7a2ae
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
1.53:1
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 -23.4
Clears Lc 15 — disabled or purely decorative text, which is not meant to be read.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 25.9
different colours
Above 10 — related only in the sense that both are colours.
What the text colour has to become
#4f4633 is the nearest colour of the same hue that passes AA on #e7a2ae, 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 1.67:1, ΔE00 17.1.
deuteranopia
Ratio 1.47:1, ΔE00 10.3.
tritanopia
Ratio 1.34:1, ΔE00 13.4.
The weakest of the three is deuteranopia, where the two are ΔE00 10.3 apart against 25.9 for a trichromat — still clearly two colours.
