Child theme color switcher
I am a designer and developer, and have a child theme that I am going to submit to the marketplace very soon. I am proficient in CSS, and have a pretty good understanding of php, and have been using WordPress since dinosaurs roamed the earth (well almost).
What's the best way to go about creating a css "picker" for a child theme? I am one to try to learn stuff myself, but if anyone could at least give me a few clues on how they did it, I would be very grateful!
Thanks very much!
