It's only a guess as I have never used it for toning but in the U.K. we can now get South African Rooibos( Afrikaans for redbush) tea. I have never seen any tea which looks as red and I suspect it might produce a nice red/brown effect.

As a tea it is an acquired taste and quite unlike any Indian tea I have tasted but OK for an occasional drink and might make a nice reddish toner
