Staining wood with aging stain?

But there is oil with color pigments, right?
No matter, I would give doors a little "more" than oil, because I would be afraid they would get greasy from use.

Yes, I also think proper paint is worth more for doors and door frames. I will do that too. After all, you keep grabbing them with your hands. Then I am also rid of the worry about which shade it will be when it darkens a bit from the oil.

But you are already tall

Yep, a whopping 1.63 m . But unfortunately, it wasn’t enough to "grow up" . And now there’s no point anymore .

It's just a question of how much it has to look alike ...

Yes, I do want uniform shades in a hallway. I haven’t grown up, but I don’t like the "crazy colorful house" look either. It should all be harmonious. I still have a few untreated pine boards. I’ll just try it out.
Thanks to everyone for the answers.

But with lacquer. The beech staircase was dyed medium gray. With the lacquer, it now looks almost black and has shifted back more towards brown. The gray tone after dyeing is completely gone.

The beech staircase became medium gray through staining. Through the varnish, it now appears almost black and it also shifted more towards a brownish tone again. The gray tone after staining is completely gone.

Hm, ... so varnishing changes the color tone again. Thanks, I'll accept that for now. I'm going to try it now on an untreated pine board... let's see Thanks, Ulrike

I'll dig up my somewhat older thread again. Maybe someone else wants to do that too.... I have now ordered three different types of stain and then "mixed" them - 1:1, 2:1, 3:1... Since all stains were made on the same base, I found nothing opposing mixing them. Once "Kirsche" and "Alterungsbeize" and then "Kirsche" and "Macore." At some point, I arrived at what I consider the right shade. For testing, I took the wood that is also used - the side of the door frame that disappears into the wall anyway. Ulrike
