Here is exactly what you have to order to get each drink made:

Purple Drink: Iced Passion Tango Tea, soy milk, blackberries and vanilla syrup

Pink Drink: Strawberry Acai Refresher, replacing water with coconut milk

Orange Drink: Orange Mango Juice mixed with two scoops of vanilla bean powder and topped with coconut milk

Green Drink: Black Tea with matcha and coconut milk

Blue Drink: Passion Ice Tea with soy milk and vanilla syrup. (Note: it's not exactly clear what makes this drink blue since it doesn't contain any fruit, so we assume you can request blue food coloring.)
