Nothing to fix
This pair already clears 4.5:1, so #44232f can stay exactly as it is. Check another pair.
And to someone missing a cone
protanopia
Ratio 10.39:1, ΔE00 69.9.
deuteranopia
Ratio 9.94:1, ΔE00 66.4.
tritanopia
Ratio 9.20:1, ΔE00 64.4.
The weakest of the three is tritanopia, where the two are ΔE00 64.4 apart against 67.6 for a trichromat — still clearly two colours.
