As far as I know, there is not a way to change to color of the bottom toolbar. There is no official way to do it, but there may be a hack to do it.
However, the toolbar at the bottom will be going away, being replaced by toolbar buttons in the header (and search will replace the header title). See this post on the Canonical design blog for further details.
