[galaxy-dev] default value for param type "color"

Hi, I've started to explore the relatively new "color" parameter type, which is not explained in the ToolConfigSyntax section of the Wiki yet. It's a pretty neat new feature, but I haven't found a way to specify a default color yet (the color selection is always set to a very light orange initially). Is this possible yet? If not I think it should really be added. Best, Wolfgang
