I imagine these are far more stylish and pared back interpretations then my generation hoped for back in the day. (Or was it just me?)
Still, the use of black makes the space feel somewhat less "childish" which I think was the point of my desire for it.
A child's room with black walls continues to be quite rare, but there are examples out there of how to do it well.
Did you go through this phase? How did your parents respond to this clash in decorating styles?
