What is the color deficiency for color-blind people?
I have some questions about color-blind people. I have a friend who is color-blinded and I am curious about what is the really color can they see through their eyes. Is it offensive or disrespectful to ask them about it? Will we become color blinded later on in our life if something happens to you or if this is caused only when you are born with?
