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
10.43:1
Passes AA for body text
AAA too. Swapping the two colours gives the same number — the ratio does not know which is the text.
APCA
Lc -81.9
Clears Lc 75 — body text at a normal size and weight.
Light text on a darker ground — the negative sign is the polarity.
Colour difference
ΔE00 76.0
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #e7dcce can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 10.31:1, ΔE00 76.8.
deuteranopia
Ratio 10.49:1, ΔE00 77.6.
tritanopia
Ratio 10.46:1, ΔE00 85.1.
The weakest of the three is protanopia, where the two are ΔE00 76.8 apart against 76.0 for a trichromat — still clearly two colours.
