Chromosphere: The Color Theory Podcast

Discussion of how our perception of blues and greens remain strong in low light, and how that may have impacted the use of lapis lazuli (and other blue pigments) prior to the invention of the electric light bulb.

Discussion of how afterimages occur when the cones of the retina tire and weaken due to overstimulation, allowing other cones to briefly play a more dominant role in vision, and how that lead to the establishment of complementary colors.

Part one of a reading of an essay I am writing, Focal Points and the Roots of Abstraction.

Human color vision adapts to the changing environment in many ways. Pupils dilate and constrict in order to regulate the amount of light entering the eye. The lens either bunches up or flattens out to change its shape while focusing light wavelengths along the spectral band at different proximities to the retina. Cone cells, and other light sensitive cells, perform plus-or-minus gains in activity to achieve what is known as color constancy, allowing humans to maintain a persistent perception of colors within changing light sources. Adaptations such as these take place at different rates of time, some more quickly than others; some more involuntarily than others, which may relate to how focal points form and dissipate within a visual field. This essay explores how adaptations of the visual system may generate focal points, and how representing light as colors informed the roots of abstraction.
