I wanted to generate many colour palette on my Garmin watch, so I made an IA for that.
I used the microgpt architecture released a few days ago. I think it works pretty well.
You can also set one or two starting colours, which is perhaps the mode where the tool is the most interesting.

I don't like the palettes it generates, but really cool (sub)domain!
