A hardware implemented method for adjusting colors of an image is provided. In this method, lookup table (LUT) values stored in an LUT are copied to a memory to create a copy of the LUT values, whereby the LUT values define the original colors of the image. Subsequently, the LUT values stored in the LUT are modified to change the colors of the image. To restore the image to its original colors, the LUT values stored in the LUT that were modified are overwritten with the copy of the LUT values stored in the memory. A graphics controller and an LUT for adjusting colors of an image also are described.
