My DH is color blind, so I don't know what he is seeing. He'll have interesting comments, like, 'It looks like molecules,' 'it looks like a box of chocolates,' 'it looks like an alien.' If I have a Bonnie Hunter quilt up, he'll say, 'Aaaahhhhh! Busy.' I'll ask his opinion when considering options for something, and then he usually says, 'it depends what you want.'
