A paint color matching and coordinating system comprises an interface for receiving an input reference color, a processor capable of reading a memory, a memory including (1) instructions readable by the processor and (2) a database of architectural paint colors spanning all or most of the known color space, and a display generator. In use, the interface of the system receives an input reference color from a user. The processor selects a “reference paint color” from the database, the reference paint color being visually closer, with respect to color space, to the input reference color than any other paint color in the database. According to the invention, color space is divided into a plurality of fixed, generally equally sized, non-overlapping, contiguous portions, each color space portion being defined as the space of all colors within a band of hues within color space. The processor selects five sets of paint colors—one set from each of the color space portions that include the five hues that comprise the “five-way harmony” of the reference paint color. The processor may also select a sixth set of paint colors from the color space portion that includes the hue of the reference paint color. Finally, the processor directs the display generator to create a display of color samples of the reference paint color and of the first through sixth sets of paint colors.
