Possibly. The problem is that it’s difficult to replace the cones in the retina. One possibility is to link your brain to a camera chip that acts like a retina, but hooking it up to your brain is difficult, but maybe possible in the future. That said, its not all bad – people with colourblindness are sometimes better at seeing details than people with colour vision. The military used to get colourblind people to look for camouflaged defences in spy plane photos.
