GUI design and colour-blindness

[Yodel]

Can anyone please advise what are the best colours to use when designing a GUI application that contains colour-coded information. I wanted to use red/yellow/green but a colleague who is colour-blind cannot distinguish the green and yellow at all. Is there a GUI standard for this?

I'm not sure about desktop applications but I'm sure the same ideas apply :

Accessibility is the key word here. And it's a bit of a pain... :o(

Essentially just go for colours with the most contrast between them. Red, Green and Blue sounds good to me.

Of course, that's for content colouring, such as bar charts. Not a good idea to use such bold colours for a general colour scheme.

Are there websites by and for colour blind people? Surely they'd give an inkling as to what colour schemes to use.

Why not use Google with "colur blind and website:"

this is a start:-
