Over at Cymbolism.com you are presented with a word and asked to pick from a pallete of widely varying color choices. Once you click on one, it then shows you the breakdown of what everyone else picked. It’s a really interesting exercise at the moment, but as they grow it will become more than that.
They have a search function that allows you to search their database for words. As they accumulate more and more words and votes this will turn into a neat design resource. Say you’re designing a car seat and you want to know what colors make people think “smart” and “safe.” This could be the place to find out. Someday. Right now, it just makes me feel yellow.
