How to Remove All the Colors Except One in GIMP

  1. Open a regular color image in GIMP by clicking “File” then “Open” and selecting the image you want to manipulate.
  2. Click “Tools,” “Selection Tools” and “By Color Select.” Click on the color you want to keep in your image.
  3. Click “Select” then “Invert” to select everything in the picture except for that color.
  4. Click “Color” and “Hue-Saturation” to bring up the hue and saturation box. Slide the “Saturation” bar all the way to the left to turn everything selected to black and white.
  5. Click “Select” and choose “None” to see your new image with only one color left.
