Perhaps chartreuse and teal?

More seriously, my understanding is that the octopus retina does not have color receptors, just aggregate light, I.e. brightness.

But the octopus practically has a sub-brain behind each respective eye, and the eye brains can extract color from the slight lensing differences across frequencies.

They are amazing magical creatures.

Taking that approach, and some sort of ocular lathe, and we can fix this.

We can always use more chartreuse.

The name sounds nice, but it's just a muddy green.

The liqueur is nicer :)

Well, you can also just give people different coloured lenses for their two eyes. Eg one that filters out red and one that filters out green.
