Palette Fades

A palette fade is a special effect in which an image's colors gradually change until they reach a set of target colors. Two similar variations, fade in and fade out, are the most popular types of palette fades. The fade in starts with an image displayed with all its logical palette values set to black, and we gradually increase the logical palette color components until they reach the image's original colors. The fade out does just the opposite: we start with the original image and gradually decrease the logical palette color components until they are all zero. This results in a completely black image.
