There are lots of directions you could go. White, beige, light grey, medium grey, mustard, orange, an accent wall that perfectly matches the headboard with main walls in a light neutral, tan...

Basically the colours you see in the photo of the bed lol.

Hi, I agree with that. I have concerns with the passage between the oblique wall and the flat walls.

I think the lighting would be important in picking the colors and design.

What you think about that wall (https://strojdizain.ru/wp-content/uploads/2017/11/bscreenshot-se4184.jpg) in combination with this floor and bed? What wood do I need to use?
