Can chrome tanned leather be dyed or vinegarooned?

Can chrome tanned leather be dyed or vinegarooned with minimum or no rub off afterwards?

It can be dyed, but I don't know about vinegroon as I don't use it

If the chrome tan is pre-dyed, I use cellulose thinners as a prep. Then I dye it.

If there isn't any tannin in the leather, vinegaroon won't work.  Maybe soak it in tea first.

@Northmount I was wondering. As there is no tannin in the leather in the first place, the tannins from tea might remain on the surface and interact with vinegaroon but bleed because there is nothing to hold it to the leather. Of course, I might be wrong about.

I've had leather jackets - chrome tan - soaked right through to my skin when I've been out in the rain for an hour or more.  I think that the tea would be absorbed into the leather if allowed to soak. 

My back was dyed blue from my soaked black leather jacket.  Took a few days and showers to get back to normal.

By the way, vinegaroon is not a dye, but a chemical reaction.  It doesn't rub off.

Even if the tea absorbs, will the tannins bind? Even after the iron acetates form, the color might bleed if damp or wet. I tried using tea once and that is what happened. Again, I might be wrong about this but my experience is that using tea and then vingaroon causes bleeding of the black color. Without the tea, it never bleeds because those tannins are bound to the leather, so there is nothing to bleed.

As with most leather dyes, paints, finishes, etc.  Do test pieces to verify what works for your leather and circumstances.
