No colour without lightLight plays an important role in the selection of colours. The quality, intensity and angle of entry of light have a profound effect on how we perceive colour in a given space. The same colour looks different in sunlight, shade and artificial light. Both natural and artificial light affect the perceived colour of surfaces, particularly light ones. Light from an incandescent bulb is perceived as warm and yellowish. In contrast, fluorescent tubes have a fairly poor colour rendition, meaning that colours lose some of their characteristics in light cast by fluorescent lamps. It is therefore advisable to select colours on site in the right lighting conditions.
Warm and light colours are more suitable on sides facing north and east, whereas relatively cold colours can be used for sides facing south and west. Other factors to be considered when selecting colours include the size and intended use of the space. What will the room be used for, who will the room be used by, and how long will people stay there? A sound rule of thumb is to select lighter and more neutral colours for living areas, such as sitting rooms and kitchens, than for rooms in which people only stay for short periods. Bolder colours can be used for effect in areas that connect one space to another. Similarly, bathrooms can be brightened up with rich shades.
