Metamerism. The word refers to the way that colors change when viewed under different light sources. And, according to the National Lighting Bureau, it’s a phenomenon that is gaining in importance, as “tunable white light” is being used continually more to mimic indoors the effects of sunlight outdoors, changing from blue tones to red tones from morning to night, helping to sync our circadian rhythms with the time of day. However, as explained in a new article by Scott Marchio of Aztec Architects, “Nothing has inherent color. Your sweater is not red, the carpet is not green, the house is not blue; color is a perception of the eye caused by a combination of reflected and absorbed light. Variables in chemical composition cause certain wavelengths of visible light to be absorbed by a material and others to be reflected. The result is a color perceived by our eyes. If you change the type of light, the temperature of light, or the rendering capacity of light, you can change the perceived color of an object…. If the lighting in a space is no longer static, but dynamic, all the finishes in a space could potentially change over the course of the day.”
While, clearly, there’s much more to be done to come to grips with new lighting technology and capabilities, when we get there, Marchio predicts, “I believe we will witness the emergence of glorious and incredible dynamic materials which will adorn every interior environment.”
