True UV color vision in a female butterfly with two UV opsins.
Journal of Experimental Biology, 2021 In true color vision, animals discriminate between light wavelengths, regardless of intensity, using at least two photoreceptors with different spectral sensitivity peaks. Heliconius butterflies have duplicate UV opsin genes, which encode ultraviolet and

Color vision in civil aviation
Indian Journal of Ophthalmology, 2021 Color vision deficiency (CVD) is a condition that results in individuals being unable to distinguish differences between certain colors. Occupational color vision standards were introduced in aviation in 1919 by The Aeronautical Commission of the ...

Evolution of Insect Color Vision: From Spectral Sensitivity to Visual Ecology.
Annual Review of Entomology, 2020 Color vision is widespread among insects but varies among species, depending on the spectral sensitivities and interplay of the participating photoreceptors. The spectral sensitivity of a photoreceptor is principally determined by the absorption spectrum

Color vision in insects: insights from Drosophila
Journal of Comparative Physiology, 2020 Color vision is an important sensory capability that enhances the detection of contrast in retinal images. Monochromatic animals exclusively detect temporal and spatial changes in luminance, whereas two or more types of photoreceptors and neuronal ...

Structural and Functional Characteristics of Color Vision Changes in Choroideremia
Frontiers in Neuroscience, 2021 Color vision is considered a marker of cone function and its assessment in patients with retinal pathology is complementary to the assessments of spatial vision [best-corrected visual acuity (BCVA)] and contrast detection (perimetry).

Optimizing colormaps with consideration for color vision deficiency to enable accurate interpretation of scientific data [PDF]
PLoS ONE, 2017 Color vision deficiency (CVD) affects more than 4% of the population and leads to a different visual perception of colors. Though this has been known for decades, colormaps with many colors across the visual spectra are often used to represent data ...

Color-discrimination threshold determination using pseudoisochromatic test plates
Frontiers in Psychology, 2014 We produced a set of pseudoisochromatic plates for determining individual color-difference thresholds to assess test performance and test properties, and analyzed the results.
