I assume it's that yellow, and that's just their humorous way of describing it. As for the 7/10 date, I assume that's just an error.
It might be an error on the webstores end as well.
Digital and CD is definitely 5/1. So far BM is the only Indie Exclusive listing I have been able to find. But the standard black pressing is popping up in a few places as 7/10. Not just BM.
