oh it has to be Green. like not too green that it barely has a taste and sticks to your teeth but, just enough for it to taste like banana but not too much. yellow is already too much for me and brown is a No for me due to the strong smell and mushy consistency (which i hate) 🙅🏻‍♀️ so the less it smells and tastes like banana the better, i’m very particular about bananas lol
