OKay I'm going to be the 'black' sheep here - I love my black viola 'Molly Sanderson'
I love very dark colours but you have to work them into your garden in a particular way to get them right.
All colours can be insipid, dull, garish, ugly, disappointing etc etc. It depends what else you associate them with.
