And the smaller size most interfaces actually use for paragraphs — the size that decides whether a pair is usable.

APCA
Lc 40.1
Clears Lc 30 — the floor: below this the draft considers text not readable at any size.
Dark text on a lighter ground.
Colour difference
ΔE00 47.6
different colours
Above 10 — related only in the sense that both are colours.
Nothing to fix
This pair already clears 4.5:1, so #330077 can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 5.05:1, ΔE00 48.6.
deuteranopia
Ratio 4.67:1, ΔE00 46.4.
tritanopia
Ratio 4.73:1, ΔE00 43.0.
The weakest of the three is tritanopia, where the two are ΔE00 43.0 apart against 47.6 for a trichromat — still clearly two colours.
