Hello,
Is there a good way to reduce the number of colors of my image to only have 4 colors? I was using indexed mode under Image but I was wondering if there was a cleaner way to do it...
See attached!
Many ways depending what you want, indexed mode is not bad at all
- Colors > Posterize...
- Colors > Dither...
- Filters > G'MIC-Qt > Testing > afre > Query Primary
- Hit the / key, input "Maximum RGB"
- Filters > G'MIC-Qt > Colors > Colormap (select custom)
That's what came to my mind, but i'm sure there are a lot more way, and the above transform the image after working on it...

I did not see it coming, Um... did not see it at all
Try the gmic plugin
http://www.gmic.eu colormap filter. Adaptive mode - dithering zero - tones 4

At least it keeps the image in RGB mode, retains some semblance to the original (98000 colours) and does actually result in 4 colours (as set in gmic)
As with all graphics, a lot depends on the original image.
