How can I invert all the display colors in Windows Vista?

"PowerStrip is the solution (not free though)

Right click the PowerStrip tray icon and select Color > Configure.

Check the Invert Gamma Ramp (negative image) box. If Write Directly to Palette DAC is not enabled, check that as well.

Optional: tweak the brightness, contrast, gamma, and temperature of the global colors or of the different components."

"Just to explain: all browsers will render web pages in the colours specified by the page author - unless you override this.

Johannes has explained where the option is in IE.

In Firefox it's at Tools > Content > Colours > Allow pages to choose their own colours, instead of my selection above.

Uncheck this option and set the text and background colours you like.

I can't seem to find the equivalent option in Google Chrome."

"Google Chrome has a high contrast extension that inverts colors on most text things on web pages while maintaining appropriate colors on most pictures and things. I use it constantly.
