See e.g., http://lists.w3.org/Archives/Public/www-style/2006Aug/0001.html
Elika and Bert decided to take over that suggestion, but simplified. There is only a fallback color for the bottom-most image. See
The editors' draft now contains a specification for
background-color: <color> [ / <color> ]?
where the second color is the fallback.' non-public [Bert Bos]
