I'm trying to modify a list of images with the terminal, I want to invert the color and apply a color with colorize, all of this with the command gimp and in the terminal. Anyone can help me?

You're going to have an easier time doing this with something like ImageMagick than GIMP on the command line.

With ImageMagick, you can use the negate command:

convert image.jpg -negate negated-image.jpg

And then colorize it:

convert negated-image.jpg -colorize 0,50,0 colorized-image.jpg
