Technicolor 3 Color Script
This script simulates the 3 Color Technicolor effect.
Copy it into the scripts folder from GIMP, you will find it then under Colors → Technicolor 3 Color.
Example here:
Updates:
- The sharpness layer got an inverted layer mask.
- I kicked the additional multiply layers out and set better default values (now R = 2R - 1/2 (B + G)).
- Values back to 1.2R. New retro colors option. Example here.
- Optional extra color layer.
