Color Vision: Mice See Hue Too
A transgenic mouse has been generated with three cone types, instead of the normal murine two. Remarkably, some of these mice use the extra cone to make trichromatic color discriminations similar to those that are the basis of human color vision.
متن کاملVariations in normal color vision. VII. Relationships between color naming and hue scaling.
A longstanding and unresolved question is how observers construct a discrete set of color categories to partition and label the continuous variations in light spectra, and how these categories might reflect the neural representation of color. We explored the properties of color naming and its relationship to color appearance by analyzing individual differences in color-naming and hue-scaling pa...
متن کاملColor constancy and hue scaling.
In this study, we used a hue scaling technique to examine human color constancy performance in simulated three-dimensional scenes. These scenes contained objects of various shapes and materials and a matte test patch at the center of the scene. Hue scaling settings were made for test patches under five different illuminations. Results show that subjects had nearly stable hue scalings for a give...
متن کاملLanthony 15-Hue Desaturated Test for screening of early color vision defects in uncomplicated juvenile diabetes.
PURPOSE To identify the most appropriate test for screening of early color vision abnormalities in uncomplicated juvenile diabetes. METHODS Enrolled in this study were 39 diabetic adolescents, characterized by optimal Early Treatment Diabetic Retinopathy Study criteria for visual acuity, transparent dioptric means and angiographically normal retinas. Color vision was examined with Standard Ps...
متن کاملFixation light hue bias revisited: Implications for using adaptive optics to study color vision
Current vision science adaptive optics systems use near infrared wavefront sensor 'beacons' that appear as red spots in the visual field. Colored fixation targets are known to influence the perceived color of macroscopic visual stimuli (Jameson, D., & Hurvich, L. M. (1967). Fixation-light bias: An unwanted by-product of fixation control. Vision Research, 7, 805-809.), suggesting that the wavefr...
