this isn't a belief, really - just the way it has always been for me ......when I visualize numbers, they are 3-dimensional and have specific colors: 5; is red; 6 is blue; 3 is yellow; 4 is brown; 2 is gray; 8 is pink; 9 is very pale gray and 1 and 10 are white; 11 is also a light gray...............after that color doesn't bear any relation to numbers for me.
