We introduce an algorithm for automatic selection of semantically-resonant colors to represent data (e.g., using blue for data about “oceans”, or pink for “love”). Given a set of categorical values and a target color palette, our algorithm matches each data value with a unique color. Values are mapped to colors by collecting representative images, analyzing image color distributions to determin...

from bygone to now, colors are aspects of nature that have been regarded scientists. in ancient greece, essence of color and its relationship with light and vision in natural philosophy and especially optics has been studied. results of greek thinkers in the field chromatics, from pythagoras to aristotle through of translating scientific and philosophical texts, received to muslim scholars and ...

In a recent paper, Everett and Borgatti (1992bl generalized their earlier (1991) definition of regular (or role) coloring of graphs. They extended their previous results to demonstrate that colorings can be used to find regular partitionings in digraphs, networks and hypergraphs. The purpose of this note is to suggest an alternative to their hypergraph representation one that requires only fami...

In this paper, we establish some connections between the concept of an equivalence of categories and that of an equivalence in a bicategory. Its main result builds upon the observation that two closely related concepts, which could both play the role of an equivalence in a bicategory, turn out not to coincide. Two counterexamples are provided for that goal, and detailed proofs are given. In par...

We study the O(N) loop model on the Honeycomb lattice with real value N ≥ 1 by means of a cluster algorithm. The formulation of the algorithm is based on the equivalence of the O(N) loop model and the low-temperature graphical representation of a N -color Ashkin-Teller model on the triangular lattice. The latter model with integer N can be simulated by means of an embedding Swendsen-Wang-type c...

To find out whether attentional target selection can be effectively guided by top-down task sets for multiple colors, we measured behavioral and ERP markers of attentional target selection in an experiment where participants had to identify color-defined target digits that were accompanied by a single gray distractor object in the opposite visual field. In the One Color task, target color was c...
