About the Color Palette
The Color Palette contains all the colors used in an image. If you edit a Truecolor or
Hicolor image, the palette displays every possible color in the spectrum. The
images here show the palettes for a Truecolor image, a 256 color image, and a 16
Grayscale image.
If an image is converted from one type of color display to another, the palette is
updated.
