[color] tag doesn't preview correctly

I know this kinda goes against forum ettique, but Discourse, supports the color tag.
Now this would be cool and all, but (on the DevForum anyway), it doesn’t appear in the preview, yet it’ll display just fine in the message itself.

[color="#777777"]hello world[/color]

From Preview Tab:

Colored text should appear in topic preview

A plugin was recently added to make more formatting options available in the editor. The color option is disabled so it doesn’t appear in the preview, but apparently the server still cooks the HTML to have the colors in it. Please use coloring sparingly because it is not intentional and will probably be removed/patched out in the future, which subsequently might break the formatting in your post if you do use it.
