Color

2000
<p>The development of terminology of color perception based on common experience has led to a science of color description and measurement. The precise measurement of color is of significance in many branches of science and technology. It serves as a record for archival description, for standardization purposes, and for matching and controlling ...

Color memory and color constancy

Journal of the Optical Society of America A, 1996
Color constancy is the perceived stability of the color of objects despite changes in the light illuminating them. An object's color is considered constant if the current perceived color is judged to be in accord with the remembered one. Thus the accuracy and precision of color memory are fundamental to understanding this classic problem.

Entropy, color, and color rendering

Journal of the Optical Society of America A, 2012
The Shannon entropy [Bell Syst. Tech J.27, 379 (1948)] of spectral distributions is applied to the problem of color rendering. With this novel approach, calculations for visual white entropy, spectral entropy, and color rendering are proposed, indices that are unreliant on the subjectivity inherent in reference spectra and color samples.

Coloring with three‐colored subgraphs

Journal of Graph Theory, 2003
AbstractLet f(n) be the minimum number of colors required to color the edges of Kn,n such that every copy of K3,3 receives at least three colors on its edges. We prove that $$(0.62+o(1))\sqrt{n}< \, f(n)< \, (1+o(1))\sqrt{n}$$, where the upper bound is obtained by an explicit edge‐coloring.

Colore. Color

2016
Taken design research in the direction of examining the surfaces of things. In his design courses, Albers defines them “the skins of materials”. These interfaces – in which are concentrated all the sensory implications of objects – determine, together with form, the sense of pleasure, a value that today seems to be prevalent in the multitude of objects

colore

2010
Nel linguaggio comune il Colore si riferisce a una speciale qualità visiva di un oggetto, percepita alla luce naturale: “la luce rapida Piove di cosa in cosa, E i color vari suscita Dovunque si riposa” . Il Colore è, in effetti, “termine indicante, in fisica, sia la sensazione fisiologica che si prova sotto l’effetto di luci di diversa qualità e ...

Complementary colors theory of color vision: Physiology, color mixture, color constancy and color perception

Color Research & Application, 2011
AbstractI describe complementary colors' physiology and functional roles in color vision, in a three‐stage theory (receptor, opponent color, and complementary color stages). 40 specific roles include the complementary structuring of: S and L cones, opponent single cells, cardinal directions, hue cycle structure, hue constancy, trichromatic color ...

Colore per Colore

2010
Nel caleidoscopico quanto frastornante susseguirsi di immagini in cui si è accecati dalla dissuasione e portati continuamente a “vedere senza andare a vedere (...) percepire senza esserci veramente” sembra che uno scopo diffuso quanto reiterato sia quello di produrre un’arte e un progetto dell’amnesia, che attecchisce rapidamente nella stanchezza del ...
