Clears Lc 75 — body text at a normal size and weight.
Dark text on a lighter ground.
Colour difference
ΔE00 92.9
different colours
Above 10 — related only in the sense that both are colours.

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 17.26:1, ΔE00 95.7.
deuteranopia
Ratio 14.20:1, ΔE00 82.0.
tritanopia
Ratio 10.93:1, ΔE00 66.8.
The weakest of the three is tritanopia, where the two are ΔE00 66.8 apart against 92.9 for a trichromat — still clearly two colours.
