Lc -73.2
Clears Lc 60 — headlines and other larger text.
Light text on a darker ground — the negative sign is the polarity.

protanopia
Ratio 6.40:1, ΔE00 49.1.
deuteranopia
Ratio 6.21:1, ΔE00 48.5.
tritanopia
Ratio 6.23:1, ΔE00 51.5.
The weakest of the three is deuteranopia, where the two are ΔE00 48.5 apart against 49.2 for a trichromat — still clearly two colours.
