You can change the background colour in your windows preferences, but you can't change the background colour of a web page.
Crossbow monitor overlays are a simple solution for reducing eyestrain and glare - they just lie flat against the screen inside your desktop monitor frame and the static keeps them in place. If for any reason they slip off, all of our monitor overlays are now supplied with four clear adhesive patches.
The colours can be combined to create deeper or mixed tints. Like all our overlays, monitor overlays have a matt and a gloss side, and can be cut down to fit your individual screen size using a guillotine.
