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?

Example:

enter image description here

I would like:

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

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

Try Filters -> Colors -> Map -> Color Exchange... in RGB mode.

You should be able to replace one color with another easily.

Do directly modify how each channel is interpreted, use Colors -> Components -> Channel Mixer To get what you want, you would select

  • Blue:
    • Red: 26.3
    • Green: 26.3
    • Blue: 26.3
  • Red:
    • Red: 93.3
    • Green: 93.3
    • Blue: 93.3
  • Green:
    • Red: 73.3
    • Green: 73.3
    • Blue: 73.3
