The first evolution of coloured ceilings typically featured a half or quarter strength of the wall colour. Since ceilings appear in shadow, using exactly the same shade as used on the walls will make the ceiling appear darker. To compensate for that, many choose a quarter or half strength of their wall colour so that the ceiling colour ends up similar weight or lighter than the walls. The Range Whites & Neutrals from Resene is ideal for this as it has strength variations of the most popular colours, so users can go up and down the strength levels to find the combination that suits.

The more recent evolution in coloured ceilings has seen strong colour either as a feature on its own, or a continuing of the wall paint colour onto the ceiling for a cocooning effect. This is particularly effective in a bedroom or media room where a dark wall and ceiling colour can make the room feel much cosier. In rooms that don't have a natural focal point, some decorators are turning to their ceiling for their feature, creating stripes and colour blocking effects, or using a dark or strong colour to contrast against lighter wall colours.

Applying a colour to the ceiling can dramatically alter perceptions of the room's space, making it appear larger, smaller, more formal or casual. A dark colour can visually lower the height of a room, while a light colour can give the impression that it's taller. Designers often use darker colours on high stud ceilings to evoke a sense of cosiness or snug retreat. A stand-alone room that can be shut off from adjoining rooms is often a stronger candidate for dark hues than primary living spaces which are often busy with other features.

When it comes to paint, a flat paint finish, such as Resene SpaceCote Low Sheen, is recommended for most projects. Flat finishes diffuse and soften the light and help to hide surface imperfections.  Waterborne enamel finishes, such as Resene SpaceCote Flat, are much more durable and easy to wipe clean than traditional acrylic ceiling flats.
