Ask the prefab house company how the process would be. Painting separately after the plastering job might then be justified, or the same work step "plastering," then disproportionate.
So my plasterer explained to me that despite the tinted plaster, it still needs to be painted once again in the plaster color. Additionally, he recommends an equalizing coat.

At least that is not generally the case. We also have colored plaster, which was not painted again.
In our case, the color was included in the price, but since it was a particular type of plaster, unfortunately not every color was possible.
All light colors were included for us, and I'll just say it straight: Either say it doesn't matter and it will be white... or take the 4000€ and you get your desired color.
I would have taken b, yes painting is cheaper later but taping everything off and then painting also simply takes time... do you really want that?
You just have to weigh how much it will bother you not to have your desired color for 2-3 years? I don't think you'll change it before then (too many other things to do).
I doubt that painting yourself later is really cheaper. We are talking about additional costs of ~10€/sqm, I looked at facade paints and you easily spend 5€/sqm. On top of that, you need scaffolding, which eats up most of the rest
We had the sample selection of our prefabricated house yesterday and also chose a color there (it had to be from the Caparol A1 color fan, for whatever reason!?). Today we were told the additional cost for it: >4,000€.
That really shocked us because we always thought that whether white or color shouldn’t matter,
