Hi Lazaro! Yes, that's a nice feature!
Some time ago, ColorSchemes.jl was split into two, prompted by the Plots folk: a barebones list of palettes (ColorSchemes.jl), and the various functions for building and modifying images - which eventually ended up in a separate repo, ColorSchemeTools.jl.
It would be interesting to compare the performance and results of your function and the one there : (https://github.com/JuliaGraphics/ColorSchemeTools.jl/blob/51b617c40ae03911e22bcb100b72a3e956e3844f/src/ColorSchemeTools.jl#L55).
I remember having to experiment with the options to get a palette which looks to my eyes a faithful representation of the image - I think clustering is a bit random?
I used to make views of movies with this function: here's the James Bond collection from a few years ago: https://imgur.com/a/AaZMV.
As a reference, here are some example of how the colours look like: https://nextjournal.com/lazarus/extracting-dominant-colours-from-pictures
I will take a look at SchemeTools later (it's also clustering ). Ahh, is the same thing. Good to know that this already there.
Nice James Bond collections :D
I do have this script to obtain colorpalettes from images (like the ones for Taylor Swift :D, https://twitter.com/drob/status/1459259255312236547 ). However, probably it will be nice to have a built-in function in ColorSchemes for this. Just in case this is of interest, here the relevant code (probably not the best approach, but it works).
