This finding may contribute to promoting emotional interaction using avatars in virtual reality-world. (2015-10-22)

Animals actively choose to match their surroundings to avoid predation
Animals can match their background to avoid detection by predators. For instance, numerous species have evolved color patterns that help them blend into their surroundings and avoid predators -- a phenomenon called crypsis. A new experimental study found that ghost crabs in the Solomon Islands may achieve crypsis by actively choosing to live in sand background that matches their body color. (2017-04-27)

Shawkey and his team sought to produce synthetic particles that mimic the tiny packets of melanin found in feathers. (2015-06-08)

Birds of a different color: Why some birds have more than one color type
In some animals, the same species can occur in two or more color types, or morphs. New research may help solve the mystery of how this can occur despite the pressures of evolution. (2016-05-03)

Caterpillars of the peppered moth perceive color through their skin
It is difficult to distinguish caterpillars of the peppered moth from a twig. The caterpillars not only mimic the form but also the color of a twig. In a new study, researchers of Liverpool University in the UK and the Max Planck Institute for Chemical Ecology in Germany demonstrate that the caterpillars can sense the twig's color with their skin. (2019-08-02)

Which piece resembles your color perception for #theDress image?
A novel algorithm to simulate the color appearance of objects under chromatic illuminants has been proposed by Ichiro Kuriki of Tohoku University. (2018-03-22)

Color is in the eye of the beholder
The unique makeup of the cells in our retina, as well as the specific physical properties of substances themselves, explain why we occasionally see things change color before our very eyes! Samo and Marko Kreft from the University of Ljubljana in Slovenia investigated this phenomenon using pumpkin seed oil as an example. They have just published their research online in Springer's journal Naturwissenschaften. (2007-07-03)

Map makers can avoid confusing the color blind
For 8 percent of men, color blindness is not just a fashion inconvenience, but an impairment that makes reading maps and other visual data difficult if not impossible. Now, a Penn State geographer has developed color schemes that allow most color-blind people to interpret the images. (2000-04-24)

Blue eyes -- A clue to paternity
Before you request a paternity test, spend a few minutes looking at your child's eye color. According to studies, published this week in Behavioral Ecology and Sociobiology, the human eye color reflects a simple, predictable and reliable genetic pattern of inheritance. The researchers show that blue-eyed men find blue-eyed women most attractive. According to the researchers, it is because there could be an unconscious male adaptation for the detection of paternity, based on eye color. (2006-10-23)

Evidence for expanded color vision for some colorblind individuals
Some forms of colorblindness may actually afford enhanced perception of some colors, according to findings reported this week in Current Biology by John Mollon and colleagues at the University of Cambridge. (2005-12-05)

More than meets the tongue
Does orange juice taste sweeter if it's a brighter orange? A new study in the March issue of the Journal of Consumer Research finds that the color of a drink can influence how we think it tastes. In fact, the researchers found that color was more of an influence on how taste was perceived than quality or price information. (2007-02-12)

Learned social preference in zebrafish
Using the zebrafish, a model organism widely used in genetic studies, researchers have found that when it comes to social interactions with other fish, individual zebrafish learn to prefer one fish color pattern over another according to their early experience with these patterns. The studies reported this week suggest that the extensive knowledge of zebrafish genetics will afford researchers an opportunity to see how genes, development, and environment lead to behaviors that mediate social interactions.

Temperature may affect pollen color
While studies on flowers' petal-color variation abound, new research looks at differences in the performance of pollen under varied environmental conditions based on its color. (2018-01-05)

Learning and memory may play a central role in synesthesia
People with color-grapheme synesthesia experience color when viewing written letters or numerals, usually with a particular color evoked by each grapheme (i.e., the letter 'A' evokes the color red). In a new study, researchers present data from 11 color grapheme synesthetes who had startlingly similar color-letter pairings that were traceable to childhood toys containing magnetic colored letters. (2013-01-23)

Color memory influenced by categories, according to new Rutgers-Camden research
While color perception universally involves the practice of categorizing colors according to basic labels, a new study at Rutgers University-Camden investigates the influence of categorization on color memory. (2015-06-23)

How carrots help us see the color orange
One of the easiest ways to identify an object is by its color -- perhaps it is because children's books encourage us to pair certain objects with their respective colors. Why else would so many of us automatically assume carrots are orange, grass is green and apples are red? (2008-07-22)

The more common the digit, the more radiant the color in grapheme color synaesthesia
A psychological phenomenon known as (2007-09-18)

Imprinting on mothers may drive new species formation in poison dart frogs

Vitiligo treated successfully with arthritis drug and light therapy
Building on prior research that examined the use of an arthritis medication to treat vitiligo, a team of Yale dermatologists has successfully applied a novel combination therapy -- the medication and light -- to restore skin color in patients. (2018-01-31)

Smithsonian finds color patterns in fish larvae may reveal relationships among species
Similarities in how different organisms look can indicate a close evolutionary relationship. Conversely, great differences in appearance can suggest a very distant relationship, as in many adult marine fish species. For the first time, however, a Smithsonian scientist has found that color patterns of different fish species in the larval stage can be very similar, revealing a closer evolutionary relationship than their adult forms would suggest. (2013-07-24)

The Role Of Music In Human Development Examined

A chameleon-inspired material that stiffens and changes color
Researchers have developed a new material that mimics the dynamic properties of skin as it tenses -- and that changes colors in the process. (2018-03-29)

Study shows that color plays musical chairs in the brain
The brain's neural mechanisms keep straight which color belongs to what object, so one doesn't mistakenly see a blue flamingo in a pink lake. But what happens when a color loses the object to which it is linked? Research shows for the first time, that instead of disappearing along with the lost object, the color latches onto a region of some other object in view -- a finding that reveals a new basic property of sight. (2009-10-01)

Sexual selection isn't the last word on bird plumage, UWM study shows
Evolutionary changes have led to both sexes becoming closer together in color over time to blend into their surroundings and hide from predators, a new study has found. (2015-03-27)

Instantaneous color holography system for sensing fluorescence and white light
The National Institute of Information and Communications Technology (NICT), the Japan Science and Technology Agency (JST), Toin University of Yokohama, and Chiba University have succeeded in developing a color-multiplexed holography system by which 3D information of objects illuminated by a white-light lamp and self-luminous specimens are recorded as a single multicolor hologram by a specially designed and developed monochrome image sensor. (2020-07-22)

Giant pandas see in color
They may be black and white, but new research at the Georgia Institute of Technology and Zoo Atlanta shows that giant pandas can see in color. Graduate researcher Angela Kelling tested the ability of two Zoo Atlanta pandas, Yang Yang and Lun Lun, to see color and found that both pandas were able to discriminate between colors and various shades of gray. The research is published in the journal Learning and Behavior, volume 34 issue 2. (2006-10-13)

Bees attracted to contrasting colors when looking for nectar
Flower colors that contrast with their background are more important to foraging bees than patterns of colored veins on pale flowers according to new research by Heather Whitney, University of Cambridge in the UK, and her colleagues. Their observation of how patterns of pigmentation on flower petals influence bumblebees' behavior, is published online in Springer's journal, Naturwissenschaften -- The Science of Nature. (2013-02-21)
