How to swap colors with GIMP


I have made an image with three colors: RGB

I want to swap each channel to a specific color. Is there a way to do that efficiently with GIMP?


enter image description here

I would like:

  • Blue: #434343
  • Red: #EEEEEE
  • Green: #BBBBBB

For GIMP 2.6.12, Just use Colors -> Map -> Color Exchange
