Blue mMerle is supposed to be Blue / Black. For me it's more Grey / Blue. Anyway I like the vintage feel about this ink. I read that Organics Studio owner tried to recreate some old Carter's recipe. He's named the ink after - I believe - his dog Ernest (called after his favourite writer - Ernest Hemingway).
