in some places you convert color codes to RGB, and in others you keep it as hex,
what is the deal with that? I know there have been some updates to the style
guide.

[Dan Beam, 2012/04/02 16:58:39]

From the style guide:
http://www.chromium.org/developers/web-development-style-guide#TOC-Color

  Hex is acceptable for shades of grey.

This isn't to say that one *can't* convert all #hex to rgb(), just that it's
currently not required by the style guide so I didn't do it (as it would've made
this CL even bigger).

Anybody that wants to do this to code they own should feel free to update it or
go about trying to amend the style guide.
