If you paste this syntax in Gimp's GEGL Graph filter you will be able to test solarization effects I made. I have no interest in transforming them into filters with GUIs as they are frankly generic. Unless of course someone shows high interest in them. In that case tell me and I will transform them into filters of their own. All of this syntax will work regardless if you have any of my plugins.

Look for the "hue" slider and modify its values.

Look for the color-overlay value=HTML code and change its parameters to be any color.
