Special Effects: Invert Colors

This option allows you to reverse the colors of your image or the selected portion of it. When you use this effect, black pixels become white, blue becomes yellow, up becomes down, and everything shifts into G-major. This is the only effect that can be undone by using it again.

For those interested in the technical side of things, this effect is performed by setting each color to its logical NOT counterpart.
