There are so many variables to this.

1. What medium are we referring to? CRT monitor, LCD monitor, printed matt page, Hi-gloss paper?
2. How much ambient light is there?
3. What type of ambient light is there? Incandescent, fluorescent, halogen...?
4. What is 'a long time'?
5. Who are we talking about? A 7 year old child, a 30 year old office worker, a 50 year old proof reader...?

Answer those questions and we won't all be shooting in the dark.

A few more important questions--- Are you sitting or standing? Wearing designer glasses or cheaters? Are you within at least 500 feet of the screen? Are you drunk or sober? Are you Obese or anorexic ?(obese people sit further away and need bolder colors-anorexics sit closer and need softer pastels) etc... Just Funny Stuff
