This script works just like the HSL adjustment Tool, but on indexed images. (I am using the same calculation Gimp uses.)

While it is relatively simple to convert in indexed image to RGB, use the HSL Tool, then convert back to an indexed image, the drawback is that the image colour index locations aren't preserved, and you need to know how many colours are in the original colormap.

This script provides the same HSL parameters and modifies the individual entries in the colourmap palette without changing the order.

Useful and interesting script, which prevents the loss of informations in color index. Thanks for sharing.
