The new top bar layout is fine, but the black color is very visually jarring/intrusive. Is using a lighter color an available option?
Make it transparent (suggestion originally from Sci-Fi meta):
Currently, this is not an available option.
But, as a workaround, userscripting should get you pretty far. Then you can have all the color-goodness you like. And let's be honest here, you really want it to be pink.
