Distribution of colors in Gallai colorings

open access: yesEuropean Journal of Combinatorics, 2020
A Gallai coloring is an edge coloring that avoids triangles colored with three different colors. Given integers $e_1\ge e_2 \ge \dots \ge e_k$ with $\sum_{i=1}^ke_i={n \choose 2}$ for some $n$, does there exist a Gallai $k$-coloring of $K_n$ with $e_i$ edges in color $i$?

Color Conversion of Wide-Color-Gamut Cameras Using Optimal Training Groups

open access: yesSensors, 2023
The colorimetric conversion of wide-color-gamut cameras plays an important role in the field of wide-color-gamut displays. However, it is rather difficult for us to establish the conversion models with desired approximation accuracy in the case of wide ...

Identification of pigments in artworks by inverse tangent derivative of spectrum and a new filtering method

open access: yesHeritage Science, 2020
Employing an economical and non-destructive method for identifying pigments utilized in artworks is a significant aspect for preserving their antiquity value. One of the non-destructive methods for this purpose is spectrophotometry, which is based on the

Estimation of dye concentration by using Kubelka–Munk and Allen–Goldfinger reflective models: comparing the performance

open access: yesScientific Reports, 2023
If the relationship between the reflectance function (K/S) and dye concentration (C) is known, the color of the dyed textile (R∞) and C could be predicted from each other.

Color terms and color concepts [PDF]

open access: yesJournal of Experimental Child Psychology, 2006
In their lead articles, both Kowalski and Zimiles (2006) and O'Hanlon and Roberson (2006) declare a general relation between color term knowledge and the ability to conceptually represent color. Kowalski and Zimiles, in particular, argue for a priority for the conceptual representation in color term acquisition.

Anisotropic Color Superconductivity [PDF]

open access: yes, 2003
We discuss the possibility that in finite density QCD an anisotropic phase is realized. This case might arise for quarks with different chemical potential and/or different masses. In this phase crystalline structures may be formed.
