Hey Innerzone. I used to think about if my red was your red, etc. and get kind of excited about it as a kid too. That we can't sense the world exactly as others do. I went to your link and was amazed at how difficult the paint chips became to distinguish in the middle sections. I scored an 11, which I guess is good, but someone else in my age range has scored a 0. Someone else scored a 1520, yikes. Fun exercise, a little taxing, but worth it to see that I have difficulty in the teal to blue color range. Funny, since those are some of my favorite colors.
