Paint is the fastest and most economical way to transform a space. A dark colour used in the right place can make a room look shorter, longer, lower or cosier than it really is. Here we explain the six visual effects we shared in our short video.
1. Dark back wall: the room gets shorter
If you paint the far (back) wall of a long room a dark colour, the wall feels closer and the room appears shorter. It is an effective method for long, narrow corridors or rooms that feel like a tunnel.
2. Half wall: the space is divided
Painting only part of a wall (for example, horizontally up to half its height or a defined area) in a different colour visually divides the space. In open-plan areas it can be used to define zones such as a work corner or dining area without building walls.
3. Dark below, light above: the walls look lower
Painting the lower part of the walls dark and the upper part light makes the walls look lower; the space feels more intimate and cosy. It is a nice solution for balancing proportions in small rooms with high ceilings.
4. Dark ceiling: the ceiling drops
Painting the ceiling darker than the walls makes it look lower than it is. It can be used to create a warmer, more enclosed atmosphere in spaces with very high ceilings. In rooms with low ceilings, the opposite should be done; we covered this in detail in our article on the perception of ceiling height.
5. Dark side walls: the room gets longer
Painting the two side walls dark while leaving the back wall and ceiling light makes the room feel deeper. The eye is drawn towards the light-coloured back wall.
6. Whole room dark: the space feels cramped
When all the walls and the ceiling are painted dark, the boundaries blur and the room feels cramped. This effect is sometimes chosen deliberately, for example in a home cinema or a cosy reading room; but it should be used carefully in general living areas.
Frequently asked questions
Which colour makes a small room look bigger?
Light, warm neutrals and painting the walls and ceiling in the same or very similar shades soften the boundaries and make the room feel spacious.
Which wall should be the accent wall?
Usually the wall that catches the eye first when entering the room, or a focal wall such as the bedhead or TV wall, is chosen.
