Excuse the mess but need ideas !

So the first picture is an idea of how we want the nusery but we’re planing to have to have the wall papered bit in grey where the cot will go and then decor there ( where the big mattress is 😂 we’re still cleaning at the mo ) and have the rest of the walls white but thinking more into it the radiator is white the window frame is white , the skirting boards are white , the cot and changing table are white so I feel that’s to much white , so I’m now struggling on colour for the walls or skirting Boards cause I don’t want to much of one colour ideas are greatly appreciated ❤️
