How can I get the color of a pixel on the screen? Not on my application, anywhere on the screen.
I know I have to use GetPixel, but how do I get the device context, that includes everything on the screen?

Any sufficiently advanced bug is indistinguishable from a feature.

Perhaps the GetPixel() function? This is a link to something I did before. Look at it, and modify it to your needs -

Code:GetDC(HWND_DESKTOP); // stupid code tags
