Raw bricks contrasted with soft brushy green plants.
Super soft minty green contrasted with a smokey brown and cream. That floating shelve mounted super-high on the wall makes the room appear taller.
Cream, greens, brown and grey. Nice balance between pattern and texture.
A modern rustic bathroom in greige, beige and brown. Cute lamps.
