Differing background colors between components in the same block

Yep this would be great to have. The main issue is we run into by having too many styling options is the final CSS file really bloats in file size. If you enable every article style in the theme, this produces a CSS file around 3.3mb which is pretty huge. At the same time having more styling options as mentioned above would allow for a lot more variety in a page so it’s something I’ll bring up with the team when we take a look at theming features for the future.
