Colors gradient not supported #7
Description
Hi! I've been using your styleguide and it works pretty well, thank you!
I've been trying to display colors gradient and it appears it's not supported. It seems only hexadecimal and rgb colors are supported, as shown in the source code here: https://github.com/stamkracht/michelangelo/blob/master/kss_styleguide/custom-template/kss-assets/js/kss.js#L120.
I think it shouldn't be too hard to add a condition to display gradients. I would happily throw a PR if you think it's cool to add this feature.
