So I've been thinking about this some more tonight, especially as a friend of mine told me she's read my last post and that she has coloured numbers.
I was discussing the number form/coloured numbers thing with Michael when I came home (he has a day form too, and an alphabet form) and realised that there are some numbers and letters which have an associated colour in my head. I didn't know I did this.
It isn't at all strong, and I don't "see" the colours in the way that I "see" the positions of days - I just have a "feeling" that certain colours go with certain numbers and letters. I don't feel uncomfortable if those letters/numbers are printed in the wrong colour, but if I was to choose colours for them to be printed in, I'd tend to pick the same ones every time. I can easily ignore it since it isn't that strong.
A is red. C is yellow, D is green. F is purple. G is brown. H is green. M is dark blue. Lower case n is green, but upper case N doesn't have a colour. S is white.
1 is white. 2 and 3 don't have colours. 4 is dark red, 5 is a mid blue. 6 is pinkish purple, 7 is green, 8 is blue (but a lighter blue than 5), 9 is pink. Bigger numbers don't have colours either, but the digits that make them usually do. (The colours I've used here aren't the exact shades by the way, just the closest ones I could find on the text palette).
C. But some are different, like the D under the staff (brown).
Interestingly the E on the bottom line is blue, but the E on the top space is white. A is red like the letter, but the As above and below the staff (not shown) aren't coloured. The F way below the staff (the lowest note an alto can reasonably be asked to sing) is dark green, the F in the bottom space much lighter mint green and the top line F isn't coloured. The higher D (second line from the top) is dark purple.
Weird, isn't it?
