APCA
Lc -44.7
Clears Lc 30 — the floor: below this the draft considers text not readable at any size.
Light text on a darker ground — the negative sign is the polarity.

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

protanopia
Ratio 6.96:1, ΔE00 50.7.
deuteranopia
Ratio 6.09:1, ΔE00 45.3.
tritanopia
Ratio 6.08:1, ΔE00 47.3.
The weakest of the three is deuteranopia, where the two are ΔE00 45.3 apart against 53.4 for a trichromat — still clearly two colours.
