In reply to Mounir.

Regarding the white text over white background and similar issues Justin, maybe the directory should enforce the use of default classes along with those custom ones used by the theme developers.

The problem with that is that the default slugs do not follow a reusable naming convention. For colors, they are things like cyan-bluish-gray, luminous-vivid-orange, vivid-green-cyan, and so on. Except for white and black, which are pretty universal names, it is a bit of a mess.
