Exterior Colour Design:
Historically the exterior colour of buildings depended to a large extent on locally available stone, bricks and pigments. In maintaining old buildings or creating new buildings it is important to have an awareness of this legacy. Some coatings companies have revived the practice of using traditional, and sometimes local, pigments.
some guidelines for exterior colour choice
The colours that can be created using traditional pigments can be described by NCS using a mapping process where each pigment is mixed with either linseed oil or with lime wash. This gives an understanding of the colours that could be achieved and those that would not fit into a historical context whether products are made traditionally or take advantage of new technology. Karin Fridell Anter made a study of many of the traditional pigments with limewash and linseed oil using the colour mapping method shown in this slide.
Colours selected for exterior use can benefit from some knowledge of traditional pigments. Colours used for facades tend to be lighter while deeper colours using more pigment may be more expensive to produce.
|This is a fragment of a city colour plan for Turin, created about 1800, which was possibly the first of its kind. Typically buildings would be coloured in the local pigment, Turin yellow, which gave uniformity to the look of an area. But a varied palette was chosen to create interest and define areas and classes of buildings.
Other countries to the north were quick to appreciate how colour could be used to enhance their cities.
