Request: (Actual) Black banner

Request Type: Change

Try to describe all current uses of the block you request to be changed. Do you foresee any issues/ problems that could result from changing the block?
Either addition or change.
Is it possible to add/change an actual fully black banner, and not the current 2 vertical stripes one we have (black and grey)?
