On modern webkit it is possible to style the console output: http://dev.hubspot.com/blog/styling-consolelog
I could take a crack at it if you'd like. I could just copy the coloring logic into the client-side version, but it would be better if it could share it's logic with the server side varient. Maybe the client-side version gets brought in by the server side one, so coloring and humanize can be shared?
Closing in favor of #98.
