Clears Lc 30 — the floor: below this the draft considers text not readable at any size.
Dark text on a lighter ground.

protanopia
Ratio 5.60:1, ΔE00 53.4.
deuteranopia
Ratio 4.33:1, ΔE00 42.0.
tritanopia
Ratio 4.00:1, ΔE00 62.4.
The weakest of the three is deuteranopia, where the two are ΔE00 42.0 apart against 63.2 for a trichromat — still clearly two colours.
