Understanding color reduction methods

When you decrease the color depth of an image, you must select a

color reduction method. Depending on the color depth you select, two

or three of these methods are available:

• Nearest Color — replaces the original color of a pixel with the

color in the newly generated palette that is closest to the original

RGB value. This method eliminates dithering and produces a high-

contrast image. This method works well with most simple

graphics.
