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.

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.

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

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 ...

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 ...

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 ...

COLORFUL TEXTILES FROM COLORFUL NATURE
BOOK OF PROCEEDINGS of the 17th Scientific – Professional Symposium and 7th International Scientific-Professional Symposium SINERGY OF TECHNOLOGY, SCIENCE & ART – THE CONCEPT OF SUSTAINABILITY AND DEVELOPMENT OF TEXTILE PRINTINGAbstract: The demands of modern life and industry strive for environmentally friendly and sustainable processes in all areas of human activity, including the textile industry. In response to this demand, natural dyes, which had fallen into obscurity at the end of the 19th century, have gained popularity as an acceptable alternative to synthetic dyes ...
