why would page not be the same color on another PC?

[razz]

Why would the pages of my program (created in VB 2008) show a different color on another computer, compared to on my computer?
I attached color sample from my PC and from another PC.
Anyone have any idea why this would happen?

I used Windows Forms to create my program.
