![]() ![]() ![]() Notice how the curves are twisting over each other? Whenever two physical samples have curves that cross at least three times, they are a metameric pair. Both curves strongly absorb blues, both absorb greens in moderation, and both are pretty strong reflectors of reds. ![]() The graph on the right shows the reflectance curves for two reds. Metameric pairs are shades thatĪppear to be identical under a single specified lighting condition but actually have different fingerprints. The resulting reflectance data is that color’s “fingerprint,” and can be used to create a reflectance curve. Using a spectrophotometer, you can measure an object to see how much light is reflectingĪt each point across the visible spectrum. Because of the increased energy in the red area, objects illuminated by incandescent lighting appear redder than those under daylight, which peaks in blue. Notice how incandescent has a lot of energy in the red area, but not much in blue. Here are the reflectance curves for incandescent and daylight. The reason for this phenomenon lies in the light source and the way the object reflects that light to give us the perception of color. To manage metamerism during color production, you need to know what causes it. As colors become lighter or more saturated, the range of possible metameric matches becomes smaller. Metameric matches are quite common, especially in near neutral colors like grays, whites, and dark colors like these. Metamerism is a phenomenon that occurs when two colors appear to match under one lighting condition, but not when the light changes. Have you ever walked out of the house wearing two black socks, only to arrive at work and realize one of them is navy blue? If so, you’ve been a victim of metamerism.
