Hi,
So after having posted a palette in this post, I played with some scripting to generate palettes for synfig and here are the result
I did generate 216 colors palettes and larger 432 colors palettes. Here is what they look like (click to enlarge ) :
It’s under CC by nc sa so feel free to mix, share, edit…
EDIT : Added a 300 colors palette, mixing each of the flavours from above.
It’s all available here : http://bambou.viens.la/colors/ as well as lot of other palette files all generated by me, all cc, feel free to mix, share…
Hope it 's useful !
