Color values don't always roundtrip correctly

[bjouhier]

If you link an input field to the colorwheel and you input #aabbcc, the value will roundtrip as #aabacc

This is fixed by https://github.com/DmitryBaranovskiy/raphael/pull/977

Hi Bruno,

Thanks for the PR's. I just moved across the country and am getting settled. Once things calm down a bit I will take a look. They look great, thanks.
