I think it depends on your [Einrichtung]. I personally find white doors the most modern, wooden doors always look a bit like country house style, I think.
We are also not fans of white doors, it generally does not fit our interior style.
Therefore, our interior doors are in smoked oak from the company JeldWen.
Smoked oak looks similar to rough-sawn oak and therefore fits very well with our furniture.
In the old house, we had old, white panel doors on which dust always settled. I found that really annoying and did not want to have it again.
