Color Concepts:As with light, color is very often underestimated in its importance for creating space. Of course one has to begin with the fact that light and color go hand in hand, a scientific phenomena that simply explained means, that without light there is no color and with changing light, how we perceive color changes too. All simple science it seems and it should be easy to obey the basic rules written for all to read, but as we know it is all too often easier said than done. It begins with the fact that all materials have their own intrinsic color and their own surface characteristics, how the light is absorbed or reflected by the color of the material can give the client, if wrongly chosen for the space, a feeling of disappointment to say the least. Often one thinks that the color cannot be a problem if the client has been given the time and the opportunity to choose his or her favourite color in advance, but if the designer has not talked to the person doing the lighting and he or she has used the wrong lighting temperature or fixture for the materials or the colors chosen, then the space can be very disappointing indeed. It is of great importance that the architect understands not only the science and the art of designing but also how color, materials and light interact. This saves costs and tears. Color can change and stimulate moods and feelings, it can calm and relax or it can infuse people with active energy, in this way we can say that color is a language, a way of communicating intentions or defining identity. When I work with clients on color concepts I make sure that we work holistically by choosing the materials and the colors in relationship to the proportions of the space and the intended use, test the compatibility of the lighting and the color in advance and never forget the daylight.
