Abstract: An assortment of color elements is grouped within a plurality of color families which are organized in accordance with a bi-radial circular color chart (FIG. 10-A) and a columnar chart (FIG. 11-A). Except for the neutral-gray color family, a pair of boundary-hues respectively defines the extent of acceptable hue variation within each group, resulting in an included range of hue within each color family, and an excluded range of hue in between neighboring color families. A color map (FIG. 17-A) serves as an index for matching system color elements to various color media and mixing formulas. Variant-hue charts enhance color comparison and selection within each main color family by displaying variations of all three color attributes, that is, value, saturation, and hue, within a single chart. Variant-hue charts also consolidate color elements into a compact format, and provide a graphical user interface for computer color selection.

Abstract: An artist's compartmented pastel case (50) and color arrangement for organizing, transporting, storing, and accessing artists' pastels, for use with computer graphics applications, and databases, as well as for use with traditional methods of painting with pastels. The case has a lid (60) which contains a removable resilient liner or pad (70) which protectively cushions and immobilizes pastels when the case is closed for transport. The color compartment arrangement (100) translates the painter's color triangle into a rectangular format by placing the three primary colors, red, yellow, and blue, in analogous locations (FIGS. 5 and 6). An empty, central compartment or current palette area (120) is provided as a place where all colors in current use can be grouped together. Empty subcompartments or holding areas (122), one located within each color compartment (FIG. 13), are also provided to hold selected pastels (172). The case's two-level construction keeps its color compartments free of dust and debris.
