What colors for the bedroom?

My bedroom is painted dark blue. I think it looks especially beautiful, especially because it is a very bright room and immediately looks so dark.

Of course I meant my bedroom :p

How about cream/light blue combined? Or a delicate turquoise? Basically, all shades of blue have a calming effect.
However, with our new house, we are breaking the mold: we will design the bedroom in white with some silver gray and otherwise 2-3 berry tones. We found a very beautiful non-woven wallpaper with these colors and will wallpaper one wall, paint the knee wall in color, and paint a nice climbing vine tattoo in [Brombeere] on the slope. For this, aubergine-colored or gray bedding, all furniture in white.

so I always find brown tones really great... painted our bedroom in brown and beige and it is calming and very modern.. maybe you can also just set accents.. stripes or something.. ;) can only recommend.. otherwise there are guides or something like that on the internet.. then it's not so hard to imagine it in your room...

We painted our bedroom in a very light shade of yellow. It looks very nice and feels calming to me. I cannot imagine our bedroom in brown tones. But that always depends on the accompanying furniture as well.

we also have one wall colored (in purple) and left everything else white. We have oak furniture and matching parquet. It turned out beautiful and, because of the one window front, also nice and bright. In general, I would recommend not using too bright colors, rather something subtle, otherwise it overwhelms you. Besides, tastes change. Maybe you should start with a light tone, which you can repaint if you don't like it anymore.
