Abstract: An objective color nomenclature is disclosed. The objective color nomenclature comprises one or more substrates of flexible material, each being associated with a color. Each substrate has a grid with a plurality of rows and columns. The first column displays a range of tones of the associated color, with each row of the column containing a particular tone. The corresponding row of additional columns contains the relative amounts of selected primary colors which comprise components of the particular tone, the percentages of primary and supplementary colors comprising the tone, and brightness information based on a selected brightness scale. The corresponding row of another column contains a unique identifier for the color, which in the current system is comprised of 361 parts, ranging from 0 to 360, representing the 360 degrees of a circle.
