Time of the day, time of the year, and the weather, all effect how we perceive colour in natural light. In interiors, the quality of the light and whether a room faces north, south, east or west add to the magic of colour. Rich warm colours can add a lively mood to a room. Warm and saturated colours appear to 'pop' and advance forwards in a space. In contrast, cooler, paler colours tend to the opposite and recede away, so adding complimentary blues or neutrals will soften the effect and create the right balance.
