How do I indicate success and failure with colour?

I need to make a Java component that turns the background a certain colour when a process passed, and another colour when the process failed.

My first thought was: green for success, red for failure.

But then I read that 10% of males can't differentiate between these two colours. What would be a better combination of colours?

(For the nitpickers: yes, I know that colour alone doesn't suffice, that text, shape, and noise can also be used. Nevertheless I am asking about the appropriate use of colour.)

I think you've answered this yourself. Use green/red in addition to text. Most people will understand green/red. If you change it to blue/yellow, the 90% who see green/red will be confused. Stick w/ the convention and add text to help the 10% who can't see green/red.

Remember that these "obvious" color associations (green=good, red=bad) are culturally variant. Thus, not relying on only the color is a very good idea.
