![]() ![]() The term has been used to describe HDR's higher color volume than SDR (i.e. It's the result of a 2D color space or 2D color gamut (that represent chromaticity) combined with the dynamic range. All impure (unsaturated hues, created by mixing contrasting colors) comprise the sphere's interior, likewise varying in brightness from top to bottom.Īrtists and art critics find the color solid to be a useful means of organizing the three variables of color-hue, lightness, and saturation (or chroma), as modelled in the HCL and HSL color models-in a single schematic, using it as an aid in the composition and analysis of visual art.Ĭolor volume The sRGB gamut projected into CIExyY color space.Ĭolor volume is the set of all available color at all available hue, saturation and brightness. ![]() All pure (saturated) hues are located on the surface of the sphere, varying from light to dark down the color sphere. The vertical axis of the color sphere, then, is gray all along its length, varying from black at the bottom to white at the top. At the upper pole, all hues meet in white at the bottom pole, all hues meet in black. Moving vertically in the color sphere, colors become lighter (toward the top) and darker (toward the bottom). Moving toward the center of the color sphere on the equatorial plane, colors become less and less saturated, until all colors meet at the central axis as a neutral gray. As in the color wheel, contrasting (or complementary) hues are located opposite each other. Pure, saturated hues of equal brightness are located around the equator at the periphery of the color sphere. The color spheres conceived by Phillip Otto Runge and Johannes Itten are typical examples and prototypes for many other color solid schematics. Many are in the shape of a sphere, whereas others are warped three-dimensional ellipsoid figures-these variations being designed to express some aspect of the relationship of the colors more clearly. Spherical coordinate system (for comparison)ĭifferent color theorists have each designed unique color solids. ![]()
