A member asked:
Supposing someone is colourblind to red, how would you know it?
A doctor has provided 1 answer
Testing: There is no color deficiency to red only - only a confusion between red and green colors. You probably would not notice it in someone else but if you have it you can compare your color choices with others. There are test booklets readily available on line which can help.
