Dwarf Fortress on Hint of Blue
#1d0200 on #cee1f2
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
14.78:1
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 86.4
Clears Lc 75 — body text at a normal size and weight.
Dark text on a lighter ground.
Colour difference
ΔE00 85.0
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #1d0200 can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 15.42:1, ΔE00 84.2.
deuteranopia
Ratio 14.44:1, ΔE00 82.6.
tritanopia
Ratio 13.57:1, ΔE00 82.5.
The weakest of the three is tritanopia, where the two are ΔE00 82.5 apart against 85.0 for a trichromat — still clearly two colours.
