Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Un*x-like operating systems.. It's 100% free, no registration required.

Are there any common guidelines howto choose a color scheme (for example foreground/background color) for terminal, emacs etc. to minimize exhaustion of the eyes? If so, is there scientific evidence for such a guideline?

In particular are there ready to use eye-friendly color schemes for urxvtand emacs?

Edit:

It would be also interesting to know, how the decision depends on the screen (matte, glossy) and on the environment (indoor, outdoor,...). In my case it is a Dell Latitude ATG which has a slightly glossy screen (not matte, but not a mirror). I use it indoors in office, in dark rooms and also outdoors.

In my case I first thought, that black font on white background is the best because the white background reduces reflections due to the glossy screen. And because black on white seems to be a high contrast. However it seems that the bright white tires the eyes...

I should point out, that I am not interested in personal opinions but in scientific evidence or at least in reasonable generally accepted guidelines based on experience.

I like the solarized colour scheme which I use for the editor and as dircolors. –  Marco Jul 19 '12 at 16:33
    
Why the close vote? –  student Jul 19 '12 at 19:07
    
The close vote is for "not constructive," ie., likely to elicit opinions rather than facts. Not mine, btw, I think the fact that you asked for evidence accompanying any answers clearly mitigates that. –  jasonwryan Jul 19 '12 at 19:54
    
I actually cast one of the close votes - it's a good question but not really on topic for U&L, since it's about color, human color perception, and eye health. –  jw013 Jul 23 '12 at 18:01
    
@jw013 ...but it's also about computers and in particular linux programs. You may say it's about the "computer-human interface", so I doesn't think that it's off-topic... –  student Jul 23 '12 at 18:18

Taken from the solorized home page:

Black text on white from a computer display is akin to reading a book in direct sunlight and tires the eye. Solarized reduces brightness contrast but, unlike many low contrast colorschemes, retains contrasting hues (based on colorwheel relations) for syntax highlighting readability.

+1. As far as I know Solarized is the only color scheme that has been engineered. It's arguable that Solarized is best because science makes it so. –  bahamat Jul 20 '12 at 17:44
