RGB color Mode

Based on the tristimulus theory of vision, our eyes perceive color through the stimulation of three visual pigments in the cones of the retina. These visual pigments have peak sensitivity at the wave length of about 630nm (red), 530nm (green) and 450nm (blue). By the comparing intensity in the light source; we perceive the color of the light. This is the base for displaying color output on a video monitor using three color primaries red, green and blue reference to as the RGB color model. The RGB color schema is an additive model i.e. intensities of the primary color are added to produce other colors. Each color points with I the bounds of the cube can be represented as the triple (R, G B) where values for R, G and B are assigned in the range from 0 to 1.shaeds of gray are represented along the main diagonal of the cube from the origin to the white vertex.

Stoke

People with diabetes are at an increased risk of stork because adversely affect the arteries, predisposing them to atherosclerosis. Over all, the risk of cardiovascular disease is two- and half times higher in men and woman with diabetes compared to people with out diabetes.In addition, people with diabetes who have stroke offer fare worse than with out diabetes. When the oxygen supply is cut off, other arteries can deliver oxygen by bypassing the blockage. In people with diabetes, however, many of the bypass arteries are also affected by atherosclerosis, impairing blood flow to the brain.
