I have noticed a little color come off on my black boots w/ both reno and venetian leather balm. I don't find it particularly concerning but am open to gentler options. haven't really tried anything else.The burnishing is not very in your face but noticeable on mine (pic below). Not too bothered about that changing, but rather about the Renovateur stripping colour generally. Which I keep hearing about from time to time on the shoe care thread.
