To pay homage to my liberal-leaning tendencies (Clinton/McCain '08), I've made it a point to try each and every "color" of tea there is. A rainbow of tea flavors, of sorts. So far, I've tried: white, black, red, orange, yellow, green, jasmine, blue(berry) and pink (grapefruit).
If you know of any good purple teas, please let me know! I'm not sure black currant tea counts.
