Thank you NVLeatherWorx. I really appreciate you took the time to thoroughly explain what you've learned. One more question. I started wiping a cushion with a concoction and can't remember what it was, but it had lemon juice. Maybe alcohol. Trying to remove any surface sealer to allow the dye to penetrate. Anyway, when the leather got wet, it turned the color I do want, then dried light again. Is there any product I could use that would do that and stay dark? Probably you'll say no. But I had to ask. Thanks!
