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
6.05:1
Passes AA for body text
Not AAA (7:1). Swapping the two colours gives the same number — the ratio does not know which is the text.
APCA
Lc 67.9
Clears Lc 60 — headlines and other larger text.
Dark text on a lighter ground.
Colour difference
ΔE00 63.5
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #005765 can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 5.39:1, ΔE00 46.1.
deuteranopia
Ratio 6.44:1, ΔE00 53.5.
tritanopia
Ratio 6.31:1, ΔE00 86.1.
The weakest of the three is protanopia, where the two are ΔE00 46.1 apart against 63.5 for a trichromat — still clearly two colours.
