I'd have thought it'd be "Lady Grey" for a female pony. Ah, but with a little checking I see it was invented in the 1990s and is trademarked by Twinnings.
there is also a flavor of tea called Lady Grey, similar in taste, and would match closer (gender-wise) than earl grey. Either way these two are adorable.
