Coloring with three‐colored subgraphs
Journal of Graph Theory, 2003AbstractLet 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.

Color memory and color constancy
Journal of the Optical Society of America A, 1996Color 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, 2012The 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.

Journal of the ACM, 1995
Summary: We describe a novel randomized method, the method of color-coding for finding simple paths and cycles of a specified length \(k\), and other small subgraphs, within a given graph \(G= (V, E)\). The randomized algorithms obtained using this method can be derandomized using families of perfect hash functions.

Objects can be recognized on the basis of their color alone by color indexing, a technique developed by Swain-Ballard (1991) which involves matching color-space histograms. Color indexing fails, however, when the incident illumination varies either spatially or spectrally.

How to color in a coloring book
ACM SIGGRAPH Computer Graphics, 1978Children's coloring books contain line drawings which a child can fill in with a crayon to produce colored pictures. Two dimensional colored areas can be produced on a raster display by an analogous method. After drawing a closed curve with line drawing commands, the graphics system can fill the area bordered by the curve.

<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 in the Dreams of the Color-Blind
The Psychoanalytic Quarterly, 1982This paper attempts to illustrate how three color-blind patients utilized color in their dreams in such a manner as to actively deny their visual defect. These patients had displaced to the eyes some critical conflicts about other body parts. The use of color to deny color blindness thus further served to deny other physical defects, both real and ...

Color spaces and color contrast
The Visual Computer, 1985With the introduction of low-cost color graphics systems comes a host of problems specifically concerned with the color aspect of the system. This paper discusses two of these problems: the selection and manipulation of colors by (possibly) inexperienced users, and the automatic selection of colors by the system to achieve high contrast effects on the ...
