Mercurial's color extension is great and all, but there isn't a list on that page of what the valid colors are. I looked for a python file named color, hoping I'd be able to read the source and see it there, but no luck. I was hoping to use grey or light grey for a color but it wasn't valid. Grey (or gray) seems like a pretty likely color to be in a list of colors.
Where can I find a list of valid colors for the color extension? Or where can I find the source for the color extension?
