Grapheme- Color Synesthesia is a jolly interesting subject. An individual's perception of numbers and letters are associated with the experience of colors. I think we all have a degree of it, like everyone has some autistic tendency, more or less noticeable.
Here each word is coloured according to the colour associated with its initial letter except for numbers and days of the week. At the moment the colours have been assigned almost at random apart from a few which have definite colours for me such as the days of the week: for me, Wednesday is definitely green! Numbers have their digits treated individually, like this: 6543

There are still a few glitches with it, of course.
