What is Chroma

Chapter 13
Interface Support for Creativity, Productivity, and Expression in Computer Graphics
Hue, value, and chroma define a color. Chroma is the perceived degree of visual difference from a neutral grey of the same lightness. It is calculated by the brightness and luminance of the pigment.

Abstract
Scientific modeling applied to the study of a mineral structure at the unit level provides a fertile ground from which to extract significant representations. 3D graphics visualization is equal part mathematics, geometry, and design. The geometric structure of 52 minerals was investigated in a specific modeling program to find if meaningful visualization pertaining to the field of art can be extracted from a mathematical and scientific resource. Working with the lines, spheres, and polygons that define crystal at the nanoscale provided the author with an exceptional environment from which to extract coherent visualizations sustainable in the art environment. The results were tested in various interactive platforms and opened a larger debate on cross-pollination between science, humanities, and the arts. Additionally, the experiment provided new ground of investigation for unexpected connections between mathematics, earth sciences, and local cultures.

Random Processes and Visual Perception: Stochastic Art
Defines the strength or dominance of a hue and its saturation. Variations in chroma can be achieved by adding different amounts of a neutral gray of the same value to alter a color.

Random Processes and Visual Perception: Stochastic Art
Defines the strength or dominance of a hue and its saturation. Variations in Chroma can be achieved by adding different amounts of a neutral gray of the same value to alter a color. CIELAB: CIELAB is the second of two systems adopted by the CIE. CIE 1931 RGB and CIE 1931 XYZ color spaces are the first mathematically defined color spaces. The International Commission on Illumination(CIE) created them in 1931. CIELAB is an opponent color system based on the earlier system of Richard Hunter. Like all CIE models, it is device independent and is used for color management as the device independent model of the ICC (International Color Consortium) device profiles.
