Jess at How About Orange always finds the coolest quizzes, and this is one she posted today. It's another "What color are you?" test, but gives your color complete with the HTML hex color code. I took it and ended up with lavender. Not only is it my favorite color, but it was also the color used as the inspiration for this site. Go figure. Extra bonus? The description is pretty much right on as well.
Another one I like (also first seen on How About Orange) is Personal DNA. It lets you use sliders to pick how strongly you feel about each section. It's kinda long, but very worth it.
