I venture that this is "highly" depending on personal predilection and the task at hand. For an exact recommendation, you need to evaluate the complete environment, the number of times that you are obliged to look elsewhere, then return to the screen and definitely of the time that you spend contemplating. > what's harmful is having to stare for hours at too much light coming > from the background... Acknowledged. A dark background permits that your eyes "defocus" and your mind can easily wander, then return to the textual or other content at display without having to turn away from the screen. Something only remotely related to the topic: Too many people use dark backgrounds then forget that a beamer will not project "black light", no matter how beautiful and ingenious they deem their ideas... ;-) This is one reason, why I abandoned dark backgrounds for most uses. Having to convert files back and forth just to allow them to have a dark background sometimes, is such dumb work... ;-> Cheerio, Michael. > On Thu, May 23, 2013 at 5:10 AM, Dave Stevens <g...@uniserve.com> wrote: >> Quoting marc dunord <marcdun...@gmail.com>: >> >>> i implore you guys/gals again! >>> >>> please implement a black-background viewing option as those offered by >>> excel and calc... >>> >>> see link below: bright screens make us sick ! :( >>> >>> >>> http://www.guardian.co.uk/science/2013/may/22/peering-bright-screens-dark-harm-health >>> >>> it would be enough to just reverse colors (like a photo negative) and >>> keep the printing as if one worked with a bright-background screen. >>> >>> as offered by pdf viewers in linux and windows... >>> >>> best >>> >>> marc >>> __________________ >> >> >> this might work for you: >> >> http://stereopsis.com/flux/ >> >> Dave >> _____________________________ >>> >>> gnumeric-list mailing list >>> gnumeric-list@gnome.org >>> https://mail.gnome.org/mailman/listinfo/gnumeric-list >>> >> >> >> >> -- >> The problem with being cynical is you can't keep up! >> >> -- anon. philosopher >> >> >> > _______________________________________________ > gnumeric-list mailing list > gnumeric-list@gnome.org > https://mail.gnome.org/mailman/listinfo/gnumeric-list > -- GnuPG/OpenPGP 2048D/74A227D5 2010-04-09 [expires: 2013-12-16] Michael Uplawski (privat) <michael.uplaw...@uplawski.eu> sub 2048g/4E580A13 2010-04-09 [expires: 2013-12-16]
