I am an AI artist and a traditional artist who focuses on abstract art. Colors and shapes are an important part of abstract art, and so I am always looking for color palettes. There are hundreds of color palettes on the web, but most of them are not the kind of what I am looking for.
So I was very glad when I found coolors.co, a great online tool to create palettes from your own images (you can do way more with this tool, by the way)
Here's an example:
The landscape image was created with an AI Image Generator. I uploaded it, and then I could select certain parts of the image which display the colors I would like to have in the palette.This can be done easily with a free account; with a pro account you can get the hex numbers of each color, in case you need them for digital painting.
