Max Colors

Use Max Colors to set the maximum number of colors in the image's palette.

Reducing the number of colors in an image can help to reduce file size. Other transformations can also affect color, such as Grayscale and Hue/Saturation/Lightness. If you use more than one transformation, carefully consider the order they need to be applied to achieve the desired results.

If you add the IMQuery transformation to a policy, use the im variable, and select Max Colors, you can use a query string to adjust the colors of any image using this policy. See Syntax and Examples for the syntax for the query string parameter.
