How to change white color to black color and black color to white color displaying from the monitor?

Any developed software? Should I write a program with APIs? (and... with which APIs?)

There may be an option in your video-adapter’s drivers/software. – Synetech Dec 13 '13 at 19:17

I'm assuming that you actually want to invert all colors, not just black and white. In Windows 7, (and probably Vista and Windows 8 too) start magnifier (Start menu → AccessoriesEase of Access, or ⊞ Win+U), click the gear icon to show settings, and check "turn on color inversion".

This only works if you're using Aero, not with the classic theme, or if your graphics driver doesn't support Aero.
