It'd be pretty neat if you could match the widget's colors with the rest of the phone. I think this would either be toggled, or automatic based on your android appearance settings (ie. whether or not you have Themed Icons enabled).
I don't think it would impact other users much, but I personally would like it as an option. For some extra visual harmony ^^

The vanadium browser (and presumably other chrome based mobile browser, but I don't use any others >.>) does this automatically with this widgets. One of theirs is also translucent, which I think might also be a nice option to have!
