As I was searching DeviantArt.com for an updated SOTAChrome script (no luck. ) I ran across these color scripts from Claire Jones. I use gimp 2.8.16 on Windows 64bit and they work for me.
The link to one of the scripts is here: http://www.deviantart.com/art/Reminisce ... -103214166
to get to the others, just click the 'view gallery' link and it should take you right to them.

There is no permission required to use them in case, you're wondering.

I also found these scripts by Jennifer Dickison: http://mommystudio.com/soft-goddess-gimp-script/
