Clears Lc 60 — headlines and other larger text.
Dark text on a lighter ground.
Colour difference
ΔE00 63.3
different colours
Above 10 — related only in the sense that both are colours.

And to someone missing a cone
protanopia
Ratio 8.31:1, ΔE00 56.6.
deuteranopia
Ratio 10.10:1, ΔE00 65.7.
tritanopia
Ratio 11.76:1, ΔE00 76.1.
The weakest of the three is protanopia, where the two are ΔE00 56.6 apart against 63.3 for a trichromat — still clearly two colours.
