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

Artisitc License Color Vision and Color hypothesis Imagine yourself in an art museum. You wander slowly from cold manner to cold room, analyzing annotateed canvases on stark white walls. When you reach a particular work, do you prefer to stand back and take everything in at once? Or do you move so wet to the painting that the individual brushstrokes become app atomic number 18nt? Several different sensational processes occur in your ace during this trip to the art museum the majority of them exact visual inputs. How does your thinker put together all the information that your look receive? This raises questions ranging from depth of field to color. The ideas of color perception and color possible action are interesting ones. How do humans account for color and does it unfeignedly exist? I think that by examining not only the neurologic on-goings in the brain, exactly by learning about color finished philosophy, and even art, a greater understanding of it can be reached. ahead delving into the philosophy of color and the questions posed by different pieces of art, the biological soil 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 optic nerves leading to the brain are a series of cells that create a lateral inhibition internet of the brightness/dark signals from the photoreceptors (1). This throws away a lot of the information generated by the photocells and gives the brain a picture of the edges of light and dark. The contrasts are created, leaving the brain to fill in the rest. Color vision is even more complex. Cones (the light adapted photoreceptor) contain three different photopigments, red, green, and blue, each corresponding to a particular wavelength of light (2). Color is a property of three things the dimension of red/green activation, blue response, and value or lightness (3). The bra in utilizes visual inputs to determine each of these, thus generating the characteristic color. One of the well-nigh 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 often given for the color of particular objects is the followers 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.
