I know that individuals who have color-blindness or complete blindness, are not able to see as vast an array of colors as most. I do understand that they can distinguish shading (dark vs. light), but I'm curious if in their dreams if they are able to experience the vibrancy of colors (since it's not delivered via the optic nerve, but rather the hippocampus)?? Would they be able to recognize color if they did (if they had blindness or colorblindness their entire lives?)
I am by no means an expert in vision or dreams so I maybe misunderstanding this completely. Please feel free to correct me, and explain how color is perceived both through physical vision and then internally as in dreams.
