well.....
The way I like to explain color blindness is like this:
Picture that you were born with blue cello film (saran wrap) over your eyes. And you learned colors based on that palette. You cannot remove it and have no frame of reference (other than black) to use to explain how a color looks. I se colors differently than you do.
People would ask me, "What does this look like to you?" There is NO way to answer that question.
Once people understand that, it makes it easier.
I also tend to give directions based on numbers or descriptions, not by color.
For example, I will never say, "Turn right at the teal house, and then left at the purple one, and I'm in the third red one on the left."
