Usabilitypost has a guide to choosing colors for your brand.
Cymbolism is a cool website you can use to see what colors people associate with different words. It works based on user votes; on Cymbolism’s home page they will display a word and displays colors next to it. Users choose the color that they associate the word to.
What is cool about this website is when you view the colors that people associate to words, such as the word calming, you can see the colors from different recent time periods.
A cool use for this would be choosing paint colors. You can see what colors people associate with a calming room or a fun room.
