APCA
Lc 84.7
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 #000044 can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 13.71:1, ΔE00 83.3.
deuteranopia
Ratio 14.52:1, ΔE00 88.0.
tritanopia
Ratio 14.55:1, ΔE00 104.6.
The weakest of the three is protanopia, where the two are ΔE00 83.3 apart against 85.0 for a trichromat — still clearly two colours.
