So there's a website called http://khroma.co/
It's one of the greatest gems I've stumbled into recently, especially as a graphic designer it's a useful tool for choosing colors, its free to use, and has artificial intelligence that understands your color preferences, and then gives you infinite choices of color combinations that go really well together, as well as match your taste.

The website design is super sleek as well. I definitely recommend checking it out if you're in need of choosing a color :)
