Artisitc License: Color Vision and Color Theory :: Biology Essays Research Papers

Artisitc authorize disguise Vision and alter Theory Imagine yourself in an device museum. You wander slowly from cold room to cold room, analyzing colored canvases on stark white walls. When you r from each atomic number 53 a particular work, do you favor to stand back and take everything in at once? Or do you move so close to the painting that the individual brushstrokes perplex apparent? Several different sensory processes occur in your heading during this trip to the art museum the majority of them involve visual in dresss. How does your brain put together all the information that your eyes receive? This raises questions ranging from depth of issue to color. The ideas of color perception and color theory are interesting ones. How do humans account for color and does it truly exist? I weigh that by examining not only the neurological on-goings in the brain, but by learning about color through philosophy, and even art, a great understanding of it can be reached. Before de lving into the philosophy of color and the questions present by different pieces of art, the biological basis process of HOW color is seen should be explained. The retina is a neural sheet, containing the photoreceptors called rods and cones that is located at the back of the eye. Between the retina and the ocular nerves leading to the brain are a series of cells that give a lateral inhibition network of the low-cal/dark signals from the photoreceptors (1). This throws by a lot of the information generated by the photocells and gives the brain a get word of the edges of light and dark. The contrasts are created, leaving the brain to fill in the rest. colorize vision is even more complex. Cones (the light adapted photoreceptor) contain lead different photopigments, red, green, and risque, each corresponding to a particular wavelength of light (2). Color is a property of three things the ratio of red/green activation, blue response, and value or lightness (3). The brain utilize s visual inputs to determine each of these, thus generating the characteristic color. One of the most important (and most interesting) conclusions of the biology of vision is that color is not technically generated by physical reality. Color appears to be a mental construct, and therefore, everyone views color differently. The rationale one is lots given for the color of particular objects is the following light consists of all colors. When light strikes an object in absorbs most of the wavelengths of light, but those that it reflects correspond to the color one sees.
