The zebrafish has a tetrachromatic vision that is able to distinguish ultraviolet (UV) and visible wavelengths. Recently, zebrafish color preferences have gained much attention because of the easy setup of the instrument and its usefulness to screen behavior-linked stimuli. However, several published papers dealing with zebrafish color preferences have contradicting results that underscore the importance of method standardization in this field. Different laboratories may report different results because of variations in light source, color intensity, and other parameters such as age, gender, container size, and strain of fish. In this study, we aim to standardize the color preference test in zebrafish by measuring light source position, light intensity, gender, age, animal size to space ratio, and animal strain. Our results showed that color preferences for zebrafish are affected by light position, age, strain, and social interaction of the fish, but not affected by fish gender. We validated that ethanol can significantly induce color preference alteration in zebrafish which may be related to anxiety and depression. We also explored the potential use of the optimized method to examine color preference ranking and index differences in various zebrafish strains and species, such as the tiger barb and glass catfish. In conclusion, zebrafish color preference screening is a powerful tool for high-throughput neuropharmacological applications and the standardized protocol established in this study provides a useful reference for the zebrafish research community.

AbstractBackground: The goal of the present study was to evaluate the color preferences of patients with schizophrenia and their correlations with personality traits. Methodology: Sixty-three patients with schizophrenia and 59 healthy volunteers were asked to undertake the color preference and the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ) tests. Results: The healthy volunteers showed a greater preference for green but a lesser one for brown compared to the patients with schizophrenia. Patients scored higher than the healthy volunteers on the ZKPQ Neuroticism-Anxiety and Activity scales. Moreover, in patients, black preference ranking was associated with the Neuroticism-Anxiety, whereas pink and orange preferences were negatively associated with Activity; white preference correlated negatively with Sociability. Conclusions: Patients with schizophrenia preferred green less but brown more, and displayed their personality correlates of these color preferences. These findings are suggesting that patients with schizophrenia should be encouraged to be more exposed to bright colors such as green and white, and less to dark colors such as black, during therapy and rehabilitation sessions.

Color Assignment

Color preferences in engineering are very important, and there exists relationship between color preference and visual comfort. In this study, there are thirty university students who participated in the experiment, supplemented by pre- and posttest questionnaires, which lasted about an hour. The main purpose of this study is to explore the visual effects of different color assignment with subjective color preferences via eye tracking technology. Eye-movement data through a nonlinear analysis detect slight differences in color preferences and visual comfort, suggesting effective physiological indicators as extensive future research discussed. Results found that the average pupil size of eye-movement indicators can effectively reflect the differences of color preferences and visual comfort. This study more confirmed that the subjective feeling will make people have misjudgment.

AbstractIt was hypothesized that Delia antiqua (Meigen), the onion fly, would show high preference in the field for trap colors reflecting visible wavelengths between 400 and 480 nm at reflective intensities above 37%. This preferred spectral zone (PSZ) was tested in an onion field in 1984, using cardboard traps painted with 11 blue, violet, and green hues, and two PSZ reflecting colors of varying intensity. It was found that colors with peak reflective wavelengths occurring between 400 and 470 nm, at or above 30% reflectance intensity, were most preferred. Wavelength-specific reflectance intensity was shown for the first time under field conditions to influence the magnitude of color preference in the onion fly.

90 students with normal color vision reported color preferences for 10 3-in. X 5-in. Munsell papers with a Munsell value/chroma of 5/6 on white, gray, or black backgrounds with a 5-in. X 7-in. visual field exposed for 2-sec. intervals. Colors of short wave lengths tended to be preferred. Preferences for colors were less extreme when colors were viewed on a black background. Illumination intensity did not reliably affect color preferences. The importance of evaluating the extent of preference differences between colors adjacent in preference orders was discussed. Background brightness and illumination did not clearly resolve differences in preference orders found in earlier studies, and the possible influence of other stimulus variables was discussed.

A three-part investigation was conducted to explore the meaning of color preferences. Phase 1 used a Q-sort technique to assess intra-individual stability of preferences over 5 wk. Phase 2 used principal components analysis to discern the manner in which preferences were being made. Phase 3 used canonical correlation to evaluate a hypothesized relationship between color preferences and personality, with five scales of the Personality Research Form serving as the criterion measure. Munsell standard papers, a standard light source, and a color vision test were among control devices applied. There were marked differences in stability of color preferences. Sex differences in intra-individual stability were also apparent among the 90 subjects. An interaction of hue and lightness appeared to underlie such judgments when saturation was kept constant. An unexpected breakdown in control pointed toward the possibly powerful effect of surface finish upon color preference. No relationship to five manifest needs was found. It was concluded that the beginning steps had been taken toward psychometric development of a reliable technique for the measurement of color preference.

Pollinator foraging behavior has direct consequences for plant reproduction and has been implicated in driving floral trait evolution. Exploring the degree to which pollinators exhibit flexibility in foraging behavior will add to a mechanistic understanding of how pollinators can impact selection on plant traits. Although plants have evolved suites of floral traits to attract pollinators, flower color is a particularly important aspect of the floral display. Some pollinators show strong innate color preference, but many pollinators display flexibility in preference due to learning associations between rewards and color, or due to variable perception of color in different environments or plant communities. This study examines the flexibility in flower color preference of two groups of native butterfly pollinators under natural field conditions. Our study reveals that pipevine swallowtails and skippers, the predominate pollinators of the two native Texas Phlox species, display distinct patterns of color preferences across different contexts. Pipevine swallowtails exhibit highly flexible color preferences and likely utilize other floral traits to make foraging decisions. In contrast, skippers have consistent color preferences and likely use flower color as a primary cue for foraging. As a result of this variation in color preference flexibility, the two pollinator groups impose concordant selection on flower color in some contexts but discordant selection in other contexts. This variability could have profound implications for how flower traits respond to pollinator-mediated selection. Our findings suggest that studying dynamics of behavior in natural field conditions is important for understanding plant-pollinator interactions.

The incidence of color deficient vision was investigated using the Pseudo-Isochromatic Plates on a relatively large and representative group. in the sample of 112 adults aged 20 to 80 yr. and comprised of 53% women and 12% minorities, 8% of men and 3% of women were color deficient. Over-all performance indicated no effects for sex or race. Nearly half of the plates were nondiscriminating among sex, minority/majority, and ”normal” and ”defective” color vision groups. Named color preferences within the ”normal” group strongly favored blues and reflected no sex differences.

The purpose of this study was to determine whether age influenced preference for the colors black and white by infants and young children. The investigator administered a color-preference test to 160 subjects who attended day-care centers and who ranged in age from 6 mo. to 4.5 yr. There were equal numbers of males and females and equal numbers of Afro- and Euro-American subjects. Ages of the subjects were controlled so there were 20 subjects in each 6-mo. age interval. Data were obtained from a 12-item test in which pairs of toys were presented to each subject. The toys were identical except that one was black and the other was white. The toy the subject selected was considered the subject's preference and the color of that toy was recorded. Results of a chi-squared test and of an analysis of variance indicated that, as a group, age affected color preference. A pro-black bias was found for the younger children. The findings suggest that color preference of infants and young children is not the same as for older children and adults.

Avian Predators

Individuals in natural populations commonly vary in color, and such color variation can be important for survival under predation pressure. Potential prey may be more likely to survive when they are cryptic against their backgrounds. Alternatively, individual coloration, regardless of background, may itself best predict predation events. Few studies have simultaneously tested the importance of crypsis and predator color preferences in explaining predation events. In this study we used objective measures of coloration to examine whether heliconia bugs, Leptoscelis tricolor Westwood, 1842 (Hemiptera: Coreidae), resembling their background were less likely to be eaten by avian predators (crypsis hypothesis). Next, we evaluated whether insect color, irrespective of background, best explains predation events (color preference hypothesis). We found the strongest evidence for the crypsis hypothesis; predators chose prey that differed most from their background in color saturation. Some evidence was also found for the color preference hypothesis; predators avoided brightly colored prey. These results suggest that crypsis can be effective in detouring predation. However, when potential prey are detected, predator color preferences may best explain predation events.
