#00ffee on #480656
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
11.52:1
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 -86.9
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 87.0
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #00ffee can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 14.39:1, ΔE00 84.6.
deuteranopia
Ratio 10.20:1, ΔE00 69.3.
tritanopia
Ratio 7.36:1, ΔE00 71.5.
The weakest of the three is deuteranopia, where the two are ΔE00 69.3 apart against 87.0 for a trichromat — still clearly two colours.
