Crepuscular on Salted Capers
#e7dcce on #a69151
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
2.29:1
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 -41.6
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 24.6
different colours
Above 10 — related only in the sense that both are colours.
What the text colour has to become
#332b20 is the nearest colour of the same hue that passes AA on #a69151, 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 2.33:1, ΔE00 25.0.
deuteranopia
Ratio 2.26:1, ΔE00 24.4.
tritanopia
Ratio 2.18:1, ΔE00 21.7.
The weakest of the three is tritanopia, where the two are ΔE00 21.7 apart against 24.6 for a trichromat — still clearly two colours.
