Hello,

Is there any GIMP tool or plugin that can be used to separate an image into groups with the same color?

This is what I'd like to achieve:



I created the layers using the fuzzy selection tool and pasting the selection as a new layer. I'd like to do something like this but with one click... like when using Filter > Enhance > Wavelet-Decompose or Colors > Components > Decompose.

Thank you!

If you have Gmic you could try Colours to Layers (Under layers) but it will put the same colours on the same layer

Hello sylyanne!

Yes, I have GMIC and I think this is a good start for what I need to do!

Thank you!
