I found a really fun and I think useful new website. When I say new I mean new to me.
Go to Color Scheme Designer three and check it out. I had a ball just moving the little dots around inside the color wheel and looking at the color schemes change on the right side of the page. I will definitely go back again and again and use this site. I hope you do to.
This site lets you play with color just like you would with a color wheel only more so. The site illustrates well the principals I was talking about yesterday and in an interactive creatively fun way.
