Summary: The molecular genetic study of Drosophila color vision circuitry has shown that pathways previously categorized as chromatic versus achromatic actually converge. Dm8 cells with amacrine-like characteristics receive direct and indirect inputs with different spectral sensitivity tuning, forming the second stage of color opponent processing.

Summary: The ability to see color at night is rare in animals, especially in vertebrates, due to the challenge of achieving sufficient visual signal-to-noise ratio in dim light. However, some insects have unique optical and neural adaptations that enable reliable color vision even in starlight. This provides advantages for nocturnal insects, particularly in discriminating night-opening flowers and may be crucial for nocturnal pollination. However, this vital ecosystem service is threatened by anthropogenic light pollution.

Summary: The presence of specific terms for blue in different languages is influenced by factors such as UV incidence and cultural complexity. Moreover, UV incidence may have a negative impact on abnormal red-green color perception.

Summary: This study investigated the effects of lighting color on thermal perception and found that deviations from CCT 5000 K can alter thermal sensation, with the most significant effects observed at 4000 K and 6500 K CCT. Additionally, it was shown that thermal perception is more sensitive to CCT changes in warm environments. The results suggest that changing lighting color could potentially change thermal sensation, skin temperature, and wettedness.

Summary: Recent advances have shown that it is possible to track visual colour processing using Linear Discriminant Analysis on patterns of EEG activity, reflecting sensory qualities, conforming to a parametric coding space, and being possible in multi-item displays. Decoding of visual colour is comparable in magnitude to the decoding of visual stimulus orientation.

Summary: The study shows that developmental prosopagnosia (DP) is not associated with deficits in color perception, with a low prevalence of color deficits in DP patients comparable to the general population. This finding constrains theories of DP that attempt to explain a wider range of visual deficits beyond face recognition.

Summary: Colour constancy refers to the ability to perceive a surface as having the same colour despite changes in illumination. This study focused on estimating the frequency of constancy failures in natural outdoor environments and found that the estimated colour appearance changed noticeably for a significant portion of the surface area in many scenes. These changes were found to be correlated with the chroma and saturation of the surfaces.

Summary: This study evaluated the accuracy of diagnosing and staging diabetic retinopathy and macular oedema among protonopic, deutronopic and tritanopic ophthalmologists. Results showed that color blindness is associated with lower accuracy in staging diabetic retinopathy and macular oedema, particularly among protonopic graders.

Summary: This study aimed to determine the reliability of a portable Bluetooth colourimeter for fruit colour measurements, characterise the changes in skin colour attributes over time in a nectarine cultivar, and evaluate the influence of row orientation and training system on nectarine skin colour. The results showed high reliability of colour estimations and highlighted the potential of h degrees as a quantitative index for monitoring ripening in nectarines. No significant effects of row orientation and training system on skin colour were observed at harvest.

Summary: Colour is a critical property of traps used to control or monitor insect pests. Applied entomologists are continuously working on improving trap colour to enhance trapping efficiency. However, human colour perceptions often differ greatly from those of the pests being studied, making trap development a laborious process heavily reliant on trial and error. This study proposes calculating insect photoreceptor responses to trap colours to guide rational trap colour optimization.

Summary: With the increasing use of digital display technology in aircraft cockpits, reliable assessment of color vision in aeromedical examinations becomes more important. Digital test methods are being used more frequently, which allows for space-saving and independent testing regardless of ambient light conditions. However, a study found poor comparability between an online app and the original analogue testing, indicating that it should not be used in a professional setting.

Summary: Ants are ecologically important insects with impressive capabilities for visual learning and orientation, able to discriminate between different colours irrespective of light intensity. However, findings across species are variable and inconsistent, indicating that our understanding of ant color vision and the role of ecological and phylogenetic factors is still in its early stages. Through compiling studies on molecular, physiological, and behavioral aspects of ant color vision, this review aims to deepen our understanding of color vision and gain insights into the colorful world of ants.

Summary: The study focused on the sensitivity of broad thorny retinal ganglion cells in primates to small moving stimuli, reconstructing the cells and analyzing their synaptic inputs. The majority of the inputs were found to come from amacrine cells, indicating their potential role in providing excitatory input to the cells.

Summary: The study compared the results of genotype analysis with the Ishihara and Hardy-Rand-Rittler pseudoisochromatic (PIC) plate tests for identifying red-green colour-deficient individuals. The combination of MassArray and PIC test results proved to be more reliable in identifying colour-deficient individuals and carriers than any single test.

Summary: Red-green color vision deficiency is the most common single locus genetic disorder in humans, affecting approximately 8% of males and 0.4% of females. This condition can be classified as dichromats or anomalous trichromats, with the latter experiencing milder symptoms and relying on three cone types. Research shows that the majority of anomalous trichromats can function without aids for color vision deficiency, in contrast to dichromats.

Summary: According to the opponent color theory, L vs. M midget retinal ganglion cells (RGCs) are better suited for black-and-white sensations rather than color sensations. A computational model demonstrates how the cortex can separate the signals from these RGCs into distinct signals for black and white using unsupervised learning. It also explains why these same ganglion cells are unlikely to mediate our perception of red and green, and suggests a theoretical alternative involving a small population of midget RGCs with input from S, M, and L cones for hue perception.

Summary: The unique hues of red, green, blue, and yellow remain unexplained mysteries in vision science. Existing physiological models attempting to predict their spectral locations have difficulties and require post hoc adjustments for unique green and unique red, as well as struggle to explain the non-linear nature of the Blue/Yellow system. A proposed neurobiological color vision model utilizes physiological cone ratios, cone-opponent normalization to equal-energy white, and a simple adaptation mechanism to accurately predict the spectral locations and variability of the unique hues.

Summary: This study compared foveal hypoplasia and EZ grades in patients with ACHM and BCM, showing a significantly higher prevalence of foveal hypoplasia in ACHM compared to BCM, and a clear difference in EZ grade distribution between the two conditions. The research highlights the role of genetic factors in foveal development, and indicates that EZ grade alone is not sufficient for definitive diagnosis.
