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.

Perhaps chartreuse and teal?
