I just finished a major redesign of this site and one of the most agonizing aspects for me was trying to pick an appropriate color scheme. It was a lot tougher than I expected to get the right tone, complement my fonts, and generally avoid clashing. Here’s a list of sites and articles that were particularly helpful:

A Simple Web Developer’s Guide To Color (Smashing Magazine) - This article pointed out simple things I hadn’t even thought of like how to match your grays to your base colors.

Coolors - A really handy color scheme generator. I really like the simplicity of it’s design.

Trendy Web Color Palettes and Material Design Color Schemes & Tools (Awwwards) - An article that analyzes Awwwards Site of the Day winner color palettes and includes a number of color resources itself.

Adobe Color CC - There are a few options to help you pick colors with a color wheel but I found Adobe’s easiest to use.

Pinterest - For me, Pinterest might have actually been the most useful site. Click through to see everything I saved to my color palettes board.
