'Iddo Pinkas' 'Claire Deo' 'Nirmala Iyer' 'Harald F. Hess' 'John A. Hammer' 'Jennifer Lippincott-Schwartz'] Title: Significance Our study reveals the intricate cellular machinery underlying structural color change in animals, as demonstrated through our investigation of the zebrafish iridophore. By employing advanced…

Animals can change their body color for various ecological functions. In fish, rapid dynamic color change is primarily known in contexts of intraspecific communication and camouflage, while examples in interspecific contexts are rare. We studied dynamic color changes and their associated behaviors in the grouper…

'Stanislav Sehnalek' 'Milan Adamek' 'Marco Leo'] This paper presents computer and color vision research focusing on human color perception in VR environments. A VR art gallery with digital twins of original artworks is created for this experiment. In this research, the field of colorimetry and the application of the…

We present a simple primary colour editing method for consumer product images. We show that by using colour correction and colour blending, we can automate the pain-staking colour editing task and save time for consumer colour preference researchers. To improve the colour harmony between the primary colour and its…

Natural selection shapes traits during evolution including animal coloration known to be important for concealment and communication and color has been particularly salient in the explosive radiation of cichlid fish species in the rift valley lakes of East Africa. Though selection can produce variation in color via…

This paper proposes a visual management scheme of medical things with a color-change radio frequency identification (RFID) tag. The color-change RFID tag employs a specific RFID tag integrated circuit (IC) and a laminated pH-indicating paper. The IC has energy harvesting and switched ground functions, which enable it…

Changes of body color have important effects for animals in adapting to variable environments. The migratory locust exhibits body color polyphenism between solitary and gregarious individuals, with the former displaying a uniform green coloration and the latter having a prominent pattern of black dorsal and brown…

'Hiroyuki Kajimoto'] Abstract— Measurement of pressure distribution applied to a fingertip is crucial for the teleoperation of robots and human computer interface. Previous studies have acquired pressure distribution by affixing a sensor array to the fingertip or by optically recording the deformation of an object.…

The colors that people see depend not only on the surface properties of objects but also on how these properties interact with light as well as on how light reflected from objects interacts with an individual’s visual system. Because individual visual systems vary, the same visual stimulus may elicit different…

'Shailendra K. Saxena' 'Swarup Roy' 'Pankaj R. Sagdeo' 'Rajesh Kumar'] Fabrication and operation of simple solid state electrochromic devices using ethyl viologen diperchlorate in a polymer matrix is presented here. In-situ Raman and transmission/absorption studies have been done to establish the origin of bias induced…

Facial color is closely linked to the perception of emotion, with reddish tones often associated with anger. While previous studies have shown that static reddish facial tones enhance this perception, it remains unclear whether dynamic changes in facial color further amplify this effect. This study investigated how…

Colour constancy needs to be reconsidered in light of the limits imposed by metamer mismatching. Metamer mismatching refers to the fact that two objects reflecting metameric light under one illumination may reflect non-metameric light under a second; so two objects appearing as having the same colour under one…

We identify the components of bio-inspired artificial camouflage systems including actuation, sensing, and distributed computation. After summarizing recent results in understanding the physiology and system-level performance of a variety of biological systems, we describe computational algorithms that can generate…

Visualization of stress and strain in polymeric materials is essential for advanced material development, and mechanochromic mechanophores (MMs)—which reversibly change their optical properties under mechanical force—have attracted considerable attention. Here, we present a flag-hinged MM based on highly emissive boron…

This study explores the mechanochromic behavior of dinuclear aluminum triple-stranded helicates with various halogenated substituents. Mechanical grinding induces distinct color changes, with powder X-ray diffraction confirming phase transitions between crystalline and amorphous states. In the crystalline phase, the…

People form associations between colors and entities, which influence their evaluations of the world. These evaluations are dynamic, as specific associations become more or less active in people’s minds over time. We investigated how evaluations of colors (color preferences) changed over the course of fall, as…

To provide a stable percept of the surface color of objects, the visual system needs to account for variation in illumination chromaticity. This ability is called color constancy. The details of how the visual system disambiguates effects of illumination and reflectance on the light reaching the eye are still unclear.…

Organic small molecules exhibiting both thermally activated delayed fluorescence (TADF) and wide-ranging piezochromism (∆λ > 150 nm) in the near-infrared region have rarely been reported in the literature. We present three emitters MeTPA-BQ, tBuTPA-BQ and TPPA-BQ based on a hybrid acceptor…

—Image or video appearance features (e.g., color, texture, tone, illumination, and so on) reflect one's visual perception and direct impression of an image or video. Given a source image (video) and a target image (video), the image (video) color transfer technique aims to process the color of the source image or video…

The production of natural pigments presents several advantages: these biomolecules can be sustainably produced, create appealing colors, and have beneficial health properties. The structural versatility of natural pigments lends them to multiple applications that align with consumer trends toward healthier and more…

Some structural colors in nature are frequently described as metallic. For example, hummingbird plumage, jewel beetles and Morpho butterflies have this attribute. While much attention has been paid to describing the often-shifting hues of these structural colors, there has been little interest in explaining why they…

Coloured indicators, whether solution or paper based, are often used in laboratory courses and academic/industrial research as a qualitative method to test important experimental markers. While useful, these tools present challenges to those with colour vision deficiency (CVD), who are unable to interpret the same…
