My DH is color blind. His world looks so much different that the one I see. In the spring the new grass is orange to him, but the leaves are green. He can't see many pastels (sp?). He is an artist and sometimes the color he uses are vivid to say the least. Once he drew a picture of our Siamese cat and the cat was a beautiful green. We have interesting conversations about colors when we want to paint the house or rooms. But we finally reach an agreement.
