Painting walls in new buildings - how often?

Hello! In my new building, the plastered walls have been painted with a layer of primer and then a layer of white wall paint. Now I would like to paint some walls in color. Do I just paint over the white? Of course, that will probably work well at first, but what will it look like in 10 years or so? Can I paint over it as many times as I want? If not, what is the best thing to do then?

Either you paint over it (2x) and can then also change the color after a few years (how often do you really do that?). Alternatively, stick painter's fleece, paint it, and if necessary just pull it off the wall and redo it.
