i've always heard the rule of thumb for font size was 1/3 the age of your intended audience.
What some some designers do not get is that a good percentage of the population has a color vision deficiency (color blind). I think it is like 8 per cent of males worldwide.
Inevitable follow-up question: Is there a correlation between user age and preferred contrast level?
All I know for rock-solid sure is that my personal pages' background color is getting lighter and lighter. 15 years ago it was ABF; it's now CDF and climbing.
