3.5 Course Overview Block
I love the new course banners in the course overview block since they expand the target area for clicks/touches, but I was curious as to why some of them are gray versus one of the other random colours. It's not particularly bothersome but I'd prefer a color as it simply stands out more to users.
I was playing around with it in a test site and it seems pretty random to me. I don't suppose in the the future a colour select option could be added? Anyway, just curious for those that are knowledgeable on this particular feature.
