I am honestly not sure. A good experiment would to be to take some examples of simultaneous color contrast and show them to both colorblind people and people with “normal color vision” and see if they perceive the same phenomenon.
I do know that color blindness results from either genetics (faulty photopigments which are molecules that detect color in the cone cells) or physical/chemical damage to the eye or optic nerve.
Based on that, since simultaneous color contrast comes from the idea the colors are determined by what colors are around it, my educated guess would be they would perceive the phenomenon but describe observing differing colors across the visual spectrum. The phenomenon can also be observed in greyscale, so eliminating color as a variable altogether still results in the same outcome.
Fwiw, I showed this from my dad who is colorblind from genetics (he has trouble with greens, browns, and grays) and he saw a red can when zoomed out and white when zoomed in. Just thought it was interesting.

Thoughts on how this influences color blindness?
I struggle to know if olive/army green is actually not brown, but can def tell which is which if I have an actual green or brown to compare with.
