The Kuler website that a friend showed me is so helpful! It allows you to find a color scheme that works well together. It is very easy to use as well. I've been using it this semester for websites to help me pick a color scheme to use. I usually decide on a main color I would like to use and then go to this website. From there I can find more color that will work well with the color I chose.
I wish I would have noticed this site earlier on in college! It would have made life so much easier.
