Coloration in Supraparticles Assembled from Polyhedral Metal‐Organic Framework Particles [PDF]
, 2022 Supraparticles are spherical colloidal crystals prepared by confined self‐assembly processes. A particularly appealing property of these microscale structures is the structural color arising from interference of light with their building blocks. Here, we

Facial coloration tracks changes in women's estradiol [PDF]
, 2015 Red facial coloration is an important social cue in many primate species, including humans. In such species, the vasodilatory effects of estradiol may cause red facial coloration to change systematically during females’ ovarian cycle.

Between coloring and list-coloring: μ-coloring
Electronic Notes in Discrete Mathematics, 2005 A new variation of the coloring problem, μ-coloring, is defined in this paper. A coloring of a graph G = (V,E) is a function f : V → N such that f(v) 6= f(w) if v is adjacent to w. Given a graph G = (V,E) and a function μ : V → N, G is μ-colorable if it admits a coloring f with f(v) ≤ μ(v) for each v ∈ V .

Orientation to the sun by animals and its interaction with crypsis [PDF]
, 2015 1. Orientation with respect to the sun has been observed in a wide range of species and has generally been interpreted in terms of thermoregulation and/or UV protection.

Proceedings of the 33rd Annual ACM Conference on Human Factors in Computing Systems, 2015 Although ubiquitous, color pickers have remained largely unchanged for 25 years. Based on contextual interviews with artists and designers, we created the Color Portraits design space to characterize five key color manipulation activities: sampling and tweaking individual colors, manipulating color relationships, combining colors with other elements ...

Cultural differences in preferences for facial coloration [PDF]
, 2017 Effects of facial coloration on facial attractiveness judgments are hypothesized to be “universal” (i.e., similar across cultures). Cross-cultural similarity in facial color preferences is a critical piece of evidence for this hypothesis.

Ontogeny of color development in two green–brown polymorphic grasshopper species
Ecology and Evolution, 2023 Many insects, including several orthopterans, undergo dramatic changes in body coloration during ontogeny. This variation is particularly intriguing in gomphocerine grasshoppers, where the green and brown morphs appear to be genetically determined ...
