E.g. some people prefer isoluminant green and red combinations that would be intolerable for most other people (for these people it prevents interference from the motor areas of the brain and helps stabilise the text). Avoiding high contrast (as Patrick said) can help (for similar reasons) and of course avoid at all costs text justification. The most important thing though as with any accessibility consideration is flexibility - avoid being prescriptive - remember people, even with the same 'condition', do not fall into neat little boxes and there are never one size fits all solutions. Ensure your text can be manipulated in the way that the individual user wants - and you can add things that make this easier like style sheet switchers etc. Jon
