I've been using Adobe Illustrator to create art for close to 30 years. (Here are some early examples of my Illustrator work.) Here's an upcoming feature called Recolor Artwork that looks really cool! I can't wait to try it.
Here is a sneak peek of a feature coming soon to Adobe Illustrator: Recolor Artwork – Color Theme Picker. The Adobe Illustrator team shares how the new Recolor Artwork tool will give designers and illustrators the ability to automatically extract colors from any image and apply them directly to designs.
