Greetings guys.

I have several .BMP files that share the same color palette.

I'd like to change several of the indexed colors from each file to have the same

So, for example, file1 has like 3 rows of indexed colors and all of them would like to be changed into one single indexed color (like pink). This could save me a lot of time changing each one of these files instead of clicking one index after another.

I'd appreciate the help if possible

hmmm.. you could try

Take one of the indexed images and adjust the colormap as required. Export it for use.

An open image shows in the palette dock. Make a note of where it is.

Open your images, choose one. Use Colors -> Map -> Set Color Map and choose the palette from the 'adjusted' image.

Onto the next image and use Filters -> Repeat Last (ctrl-f)

If that works with your images there is a script that saves all open images. Otherwise it might be possible with ImageMagick but I need to look that up.
