APCA

different colours
Above 10 — related only in the sense that both are colours.

And to someone missing a cone
protanopia
Ratio 12.18:1, ΔE00 92.6.
deuteranopia
Ratio 10.84:1, ΔE00 86.3.
tritanopia
Ratio 11.04:1, ΔE00 72.1.
The weakest of the three is tritanopia, where the two are ΔE00 72.1 apart against 93.4 for a trichromat — still clearly two colours.
