Weird issue with a css classname that is a css color that follows certai...

...n hex colors.

I was having a weird issue where the regex for replacing color names was eating up too much css creating a declaration that was incredibly invalid.  The new regex helps but it still replaces classnames/IDs that match a color name in the css colors array.

Additionally I added error catching to the color -> lab format conversion which would have really helped when identifying this issue.
