I am learning GIMP since I've started to print my t-shirts.

My question is how can I keep the colors of an image after Maximize RGB?

For example for an image with a rainbow, I am taking out the background then save the image in Maximize RGB. Colors become more red and blue, but I want to keep original colors.

    Then do not use "Maximum RGB"? – Jongware Mar 23 '18 at 21:44
  • Can you please show some example images of what you are trying to achieve? – Billy Kerr Mar 24 '18 at 11:28

May be describe really what you want to do (with example pictures) because Maximize RGB is likely not the way to do it. If you want to reduce the number of colors in the picture:

  1. Color>Posterize but this will find the most common colors
  2. Create a palette with the color you want, then Image>Mode>Indexed, check Custom palette and give your palette. Try the dithering options.
  • Thank you for your answers. Meanwhile I've found out what was going on. I wasn't aware that every image I'll save from GIMP will be automatically be in RGB. And because I didn't know, I was converting every image in Maximize RGB (the instruction were like if you use Photoshop, save image in RGB; for alternatives like GIMP do the same). Now is great, because all my images are keeping their colors. Thank you again and all the best! – WATERMELON Mar 25 '18 at 3:21
