Abstract: 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.

Abstract: An architectural paint color display system comprises a plurality of displays each having a two dimensional array of architectural paint color samples showing paint colors from only one of a plurality of non-overlapping contiguous portions of a color space. Each of such color space portions is defined as the space of all colors within a band of hues within the color space. Each of said color space portions is exclusively represented by one of the displays, and each of the displays represents only one of said color space portions, such that there is a one-to-one correspondence between displays and color space portions. The paint color samples have in one dimension of the arrays an increasing value and in the other dimension of the arrays an increasing chroma. The displays are preferably arranged in a three-row or six-row matrix. Each row of the matrix displays color space portions in the same sequence that such portions appear in the color space.

Abstract: A neutral paint colorant has a composition comprising approximately 7.0% Color Index Pigment Yellow 42, 2.4% Color Index Pigment Red 101, and 4.0% Color Index Pigment Black 7. A pre-blended mixture of the neutral colorant and a paint base can be blended with a first paint to form a second paint having substantially the same hue and value (lightness) as the first paint, but a lower chroma (brightness).
