Yes, I have used subjective color to get 5 color blind people to see
colors they have never seen before.
Blue for blue/yellow color blind. Red for red/green color blind.
For the totally color blind student
I did not succeed, but he did report see a color he had never seen
before. The color did not match
with the normal situation, ie. same reports for the non-color blind.
The most interesting report was the student who had lost his
yellow/blue color vision due to a brain injury when he was a child.
He reported seeing blue again and remembering that blue was blue.
This suggest that our experience of redness may be related to others
experience of redness.
