I was wondering how do you make the color "radioactive" in Gimp 2 accurately? I want to be sure and not mess up.

Search for a Toribash color pallette.

there is a "usefull threads" sticky in the art board, with links to usefull threads related to the art board

the gimp colour palletes are in there.

Don't worked in gimp 2.8

Here. Enjoy.

Edit: Found out. Madnesss made this, so he gets all credit.
