Demo: https://harmony.sh/ https://harmony.sh/ Feedback: The complimentary color stuff is useful, it's been on sites like Kuler/Adobe Color for a long time (with a much better implementation). This is not really a real UI widget project you could actually use. It's really annoying you can't click one of the secondary circles to switch the color picker to that point. Also not really usable as a UI element because you can't copy/paste hex. Or make dark colors such as black.
