Soy and passion tea make purple. The "Purple Drink" used to be a thing. Not official, but it definitely got ordered enough! Just missing the vanilla.

I got you
So get your shaker and rinse it out, pour passion until the base line and then add soy from the water/lemon/tea lime, I would do a light scoop of ice. Shake it all up and while pouring hold some ice back. Then you get the nonfat milk (or if you’re sweet cream) I don’t pour a lot of milk in the foam blender because we don’t use a lot, so I barely cover the silver point in the middle, then add about one scoop of matcha. Add the foam and then put the nitro lid on it :)
