Dwarf Fortress on Master Sword Blue
#1d0200 on #00ffee
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
15.59:1
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 90.4
Clears Lc 90 — the level the draft treats as a maximum worth targeting for body text.
Dark text on a lighter ground.
Colour difference
ΔE00 93.7
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 18.06:1, ΔE00 93.1.
deuteranopia
Ratio 14.32:1, ΔE00 82.1.
tritanopia
Ratio 10.60:1, ΔE00 72.2.
The weakest of the three is tritanopia, where the two are ΔE00 72.2 apart against 93.7 for a trichromat — still clearly two colours.
