Location of the interior in relation to directions.
The imperfections of the walls are easier to hide under light colours, with little saturation. In East and South oriented interior’s intense colours are the safe choice in order for them not to seem too white in the strong morning and midday sun. South oriented interior where the light is present throughout the day, darker, saturated colours can be freely used. When choosing colour into West oriented interiors it’s necessary to take into account the orange light of the setting sun. For North oriented interior where are rooms without sufficient light, illuminating the interior with bright colours, for example yellow derivatives are suggested.
