Color Space Book

It has been postulated that humans can differentiate between millions of gradations in color. Not surprisingly, no completely adequate, detailed catalog of colors has yet been devised, however the quest to understand, record, and depict color is as old as the quest to understand the fundamentals of the physical world and the nature of human consciousness. Rolf Kuehni’s Color Space and Its Divisions: Color Order from Antiquity to the Present represents an ambitious and unprecedented history of man’s inquiry into color order, focusing on the practical applications of the most contemporary developments in the field. Kuehni devotes much of his study to geometric, three-dimensional arrangements of color experiences, a type of system developed only in the mid-nineteenth century. Color spaces are of particular interest for color quality-control purposes in the manufacturing and graphics industries. The author analyzes three major color order systems in detail: Munsell, OSA-UCS, and NCS. He presents historical and current information on color space developments in color vision, psychology, psychophysics, and color technology. Chapter topics include: A historical account of color order systems Fundamentals of psychophysics and the relationship between stimuli and experience Results of perceptual scaling of colors according to attributes History of the development of mathematical color space and difference formulas Analysis of the agreements and discrepancies in psychophysical data describing color differences An experimental plan for the reliable, replicated perceptual data necessary to make progress in the field Experts in academia and industry, neuroscientists, designers, art historians, and anyone interested in the nature of color will find Color Space and Its Divisions to be the authoritative reference in its field.

DIVA comprehensive handbook of all the crucial information interior designers need to know on a daily basis. In the world of interior design, thousands of bits of crucial information are scattered across a wide array of sources. Color, Space, and Style collects the information essential to planning and executing interiors projects of all shapes and sizes, and distills it in a format that is as easy to use as it is to carry. Section 1, Fundamentals, provides a step-by-step overview of an interiors project, describing the scope of professional services, the project schedule, and the design and presentation tools used by designers. Section 2, Space, examines ways of composing rooms as spatial environments while speaking to functional and life-safety concerns. Section 3, Surface, identifies options in color, material, texture, and pattern, while addressing maintenance and performance issues. Section 4, Environments, looks at aspects of interior design that help create a specific mood or character, such as natural and artificial lighting, sound and smell. Section 5, Elements, describes the selection and specification of furniture and fixtures, as well as other components essential to an interior environment, such as artwork and accessories. Lastly, section 6, Resources, gathers a wealth of useful data, from sustainability guidelines to online sources for interiors-related research. Throughout Color, Space, and Style appear interviews with top practitioners drawn from across the field of interior design./div

Discusses the basics of the Photoshop LAB colorspace, describing LAB's role in colorspace conversions, providing techniques to create color variation, and including the use of "imaginary colors."

From the vital voice of Elijah Anderson, Black in White Space sheds fresh light on the dire persistence of racial discrimination in our country. A birder strolling in Central Park. A college student lounging on a university quad. Two men sitting in a coffee shop. Perfectly ordinary actions in ordinary settings—and yet, they sparked jarring and inflammatory responses that involved the police and attracted national media coverage. Why? In essence, Elijah Anderson would argue, because these were Black people existing in white spaces. In Black in White Space, Anderson brings his immense knowledge and ethnography to bear in this timely study of the racial barriers that are still firmly entrenched in our society at every class level. He focuses in on symbolic racism, a new form of racism in America caused by the stubbornly powerful stereotype of the ghetto embedded in the white imagination, which subconsciously connects all Black people with crime and poverty regardless of their social or economic position. White people typically avoid Black space, but Black people are required to navigate the “white space” as a condition of their existence. From Philadelphia street-corner conversations to Anderson’s own morning jogs through a Cape Cod vacation town, he probes a wealth of experiences to shed new light on how symbolic racism makes all Black people uniquely vulnerable to implicit bias in police stops and racial discrimination in our country. An unwavering truthteller in our national conversation on race, Anderson has shared intimate and sharp insights into Black life for decades. Vital and eye-opening, Black in White Space will be a must-read for anyone hoping to understand the lived realities of Black people and the structural underpinnings of racism in America.

This lecture describes the author's approach to the representation of color spaces and their use for color image processing. The lecture starts with a precise formulation of the space of physical stimuli (light). The model includes both continuous spectra and monochromatic spectra in the form of Dirac deltas. The spectral densities are considered to be functions of a continuous wavelength variable. This leads into the formulation of color space as a three-dimensional vector space, with all the associated structure. The approach is to start with the axioms of color matching for normal human viewers, often called Grassmann's laws, and developing the resulting vector space formulation. However, once the essential defining element of this vector space is identified, it can be extended to other color spaces, perhaps for different creatures and devices, and dimensions other than three. The CIE spaces are presented as main examples of color spaces. Many properties of the color space are examined. Once the vector space formulation is established, various useful decompositions of the space can be established. The first such decomposition is based on luminance, a measure of the relative brightness of a color. This leads to a direct-sum decomposition of color space where a two-dimensional subspace identifies the chromatic attribute, and a third coordinate provides the luminance. A different decomposition involving a projective space of chromaticity classes is then presented. Finally, it is shown how the three types of color deficiencies present in some groups of humans leads to a direct-sum decomposition of three one-dimensional subspaces that are associated with the three types of cone photoreceptors in the human retina. Next, a few specific linear and nonlinear color representations are presented. The color spaces of two digital cameras are also described. Then the issue of transformations between different color spaces is addressed. Finally, these ideas are applied to signal and system theory for color images. This is done using a vector signal approach where a general linear system is represented by a three-by-three system matrix. The formulation is applied to both continuous and discrete space images, and specific problems in color filter array sampling and displays are presented for illustration. The book is mainly targeted to researchers and graduate students in fields of signal processing related to any aspect of color imaging.

Colors are an element of both the natural and the man-made environments. They convey messages of all kinds and perform a wide variety of functions, informing, organizing, warning. But they also serve an aesthetic purpose, affecting the statement, effect, and acceptance of objects and spaces. While people’s reactions to color vary widely, in design questions it is still possible to establish generally valid color concepts to match the expectations of the various groups of users. This book offers a guide based on a wide range of scientific findings and may be consulted as an authoritative reference by the architecture student and the professional alike. The three editors, Dr. B. Rodeck, Prof. G. Meerwein, and F. H. Mahnke have taught for many years at the Salzburger Seminare für Farbe und Umwelt der IACC.

With a fleet of telescopes in space and giant observatories on the ground, professional astronomers produce hundreds of spectacular images of space every year. These colorful pictures have become infused into popular culture; we find them on billboards, in commercials, and on our computers. But they also invite questions: Is this what outer space really looks like? Are the colors real? How are these images made? "Coloring the Universe" uses accessible language to describe how these giant telescopes work, what scientists learn with them, and how they are used to make color images. Both informative and beautiful, this book is filled with brilliant images of deep space as well as an insider s perspective by the people who make them."
