I'd also choose Earl-Gray^WBlack, though a nice green-mint will do fine on a warm afternoon.

I think you missed the "Whatever color the taste gives it" category, like fruit-teas (Mango, Strawberry, Pineapple & Lemon, Blackcurrant, ...), spice-teas (Cinnamon, Caramel, Vanilla, ...) and other vague flavors like "Rooibos", "Double Green" (green tea with cuecumber), "Turkish Apple" or "Minty Morocco" where nobody really knows what is making the tea tastes as weird as it does.
