WE had a friend who couldn't really tell browns & reds. He was always wearing pink socks & shirts, which was funny b/c he was the image of man. Burly, like the guy on the brawny paper towels... We would tease him endlessly. Also, apparently he accidentally painted his shutters on his house pink but didn't know until his friend dropped him off from work one day & asked why his shutters were pink. He was mad at his ex wife for a while over that one!
My dad has sort of the opposite problem - he sees colors very differently b/c he is a printer on a 4 color press, so he sees everything in different shades than normal people. More detailed, maybe. I "inherited" a little bit of this wierdness, as is evidenced by a long-standing argument over an orange couch we used to have that my husband insisted was pink, but I thought was more orange/salmony.
Are we all looking at the same tree?
