I know people from uni that had colour trouble, I don't.
Its not a question of colour trouble, its a question of giving you the best chance of pattern reconistion. I not saying you might be bad at some colours, just that you may be better at others.Even people without dyslexia will be better/worse at reading when presented with different colour combinations. In fact for differnt colours not to make a difference means that you do have a problem with colour, cos your pattern recognition is just as bad with all of them.
Anyone remember the Lightening Forth manual?
