Dark Blue Entrance
Give the illusion of a large wall by camouflaging a door.
Move away from the expected gallery-white art wall and saturate a single wall, including any doors and trim, in a bold, can't-be-missed colour, like this cobalt blue. Carry the display across by painting out a door for a hidden-passage feel. A canary yellow settee cranks up the contrast and also draws attention away from the door.
