The main (and I think only current) "Green Lantern" book is about Hal Jordan, the 2nd white Lantern. Just about every major character that started out as white, still have their own titles.
Come to think it, DC doesn't have any POC characters leading their own books, or major ones, right now. Note: I said major; Naomi & Silencer doesn't count.
So, in other words, bait thread.
