As an oil painter in the realist figurative tradition, I place a premium on mixing and applying colors in the correct balance and gradations. The Munsell color system offers conceptual and practical support in these endeavors. Massachusetts Normal Art School instructor Albert Munsell developed the system in the late 19th and early 20th centuries.
In defining a three-dimensional model of colors, the system formulates a precise way of understanding color based on its main components: value, chroma, and hue. By extension, the system offers vital insights into color combinations, color balance, and complementary colors. As defined in the Munsell Book of Color, complementary colors are actually opposite hues. The Munsell system arranges hues in a circular horizontal plane. Drawing a straight line through any two points in the circle, running through a neutral central pole, defines which two hues are complementary. These two colors provide the strongest possible contrast to each other, yet when mixed, they create an almost neutral gray.
The artist can also draw a line between any two hues on the circle without passing through the central axis. Drawing a line out to the circle at a 90-degree angle from the center point provides the hue derived from mixing these 2 hues. Hue is just one component of overall color, and the three dimensionality of the Munsell system allows additional elements of color to be defined. Chroma, or purity of color, is measured radially from the central neutral pole within the circular horizontal plane and within hue-specific bands.
Thus, each segment of chroma moving outward represents an increased purity of color within a particular hue. Interestingly, due to what is visible to the human eye, some colors have a larger number of potential chroma than others. For example, light yellows have a significantly larger number of possible chroma than light purples. The third element of color is value, which is measured along the central neutral pole. The positioning of the horizontal hue-and-chroma elements along this vertical value axis defines colors’ lightness and darkness.
The Munsell color system illustrates that some hues have a greater effect than others. Red is an example. For this reason, an artist seeking ideal contrast and color balance might try matching a weak chroma of this hue with a strong chroma of its opposite hue. Ideally, any color system constitutes a starting point from which to gain a fuller understanding of color in painting and to develop analytical habits of balancing and matching colors. With complicated color schemes, even the strongest adherent to the Munsell color system will find it advantageous to throw a good deal of intuition and inspiration into the mix.
