Perceptions of color, including red and green, are determined by how the brain interprets signals from the eyes. Blind people, depending on the nature and extent of their blindness, may not perceive color at all. Those who are completely blind (no light perception) do not see colors. In cases of partial blindness where some light or shape perception is possible, interpretations of color can vary greatly. Essentially, the question of seeing red as green doesn't apply in the traditional sense, as color perception requires the ability to see light.
