Like Lena, katy, Bewildered (and somewhat like Ericka) I too have always associated digits with colors. 0=white, 1=gray, 2=red, 3=green, 4=yellow, 5=brown, 6=maroon, 7=silver, 8=blue, 9=orange. Letters of the alphabet, too. I recently read about the brain condition synesthesia, in which senses are mixed, and wonder if this is related.
