PixelGetColor different on another computer?

[Krustbox]

I made myself a program which is heavily based on checking pixel colors in different locations, and when i tried it on another computer it doesn't work, as if the colors on the other computer aren't the same? What is the cause of this? Is there a better way of programming something instead of using pixelgetcolor?

Well if the 2 computers have different wallpapers of course the colors are different. They could be running a different os, theme. They might not even both be using the same Color Depth.

Well all the colors are based off the same program, no wallpaper involved. both computers using 32 bit color and everything. I don't see why the color should be any different. it's the exact same program and color pixel location.

Screen resolution?

If it's a Windows 7 system, I think I've seen it mentioned in the forums that Aero may cause issues in Pixel color recognition.

Still plenty of reasons why it might not work.
