Let’s talk about one coloured walls today. I don’t mean just simply painting a wall in one colour, but also adding for example shelves or letters. Monochrome painting. If you want to make a letter statement, but don’t want it to stick out too much, simply paint the letters the same colours as the wall.
The same goes for shelves. If you want to draw attention to what’s on the shelves, more than the shelves themselves, paint the shelves the same colour as the wall just like here. It looks like the shelves are a part of the wall.
