Easy enough to do! If you want first-hand details on the processing of the fake blue tea, read one of Robert Fortune's fascinating journals, which read as half botany lesson and half adventure novel (he goes from describing the flowers in the hills around Hong Kong to fighting off river pirates while under a high fever).
As for some discussion of blue teas, Marriage Freres of all places has a nice account in their book/catalog. They even still call their oolong section "blue teas."
