I tend to agree with fever. I'm dyslexic and I find coloured text much harder to read than simple well spaced text. Plus coloured text is expensive to print in colour and when printed in B&W it looses contrast when compared with plain B&W text.

I've tried lots of syntax highlighting tools for code, HTML and XML, and I often find I think it's cool and better than plain unadorned text, until I use it, then I prefer light text (one of only a few colours) on a dark background.

The various societies for dyslexia, blind/partial sighted and reading/learning problems, all have guidelines (often conflicting I might add), but they tend to suggest simple high contrast colours well spaced.

While I accept that you can do what you want on your own when you work on code, when you present it, indeed when you present anything, it's all about clear simple presentation. The same rules that make an article or presentation good apply to anything, code or not.
