![]() When saturation is 255, the color is fully saturated. The saturation of a color refers to the extent it departs from a neutral color such as gray, or in simpler terms, its colorfulness. Saturation is given as an integer from and including 0 to 255 (representing 0 to 100 percent). Saturation-Specifies the intensity of saturation to which the color will be set.This is resampled from the values 0° to 360° in which the hue is given as an angle counterclockwise around the color cone. Hue is given as an integer from and including 0 to 240. Hue-Specifies the hue (color) to which the color will be set.In the HSV color model, the following are true: The three components of the cone are hue, saturation, and value as shown in the following illustration: The HSV color model is based on a color system where the color space is represented by a single cone. Approximately 20 shades of gray are discernible by the human eye. This leaves values 1 through 254 available indexes for shades of gray. If all three values are set to 255 (255,255,255), the total presence of color illuminates white, and conversely, if all three color values are set to 0, the absence of color illuminates black. In the RGB color model, pure gray shades are obtained by combining equal quantities of all three color values: red, green and blue. A color with blue set to 255 will appear bright blue, or fully saturated with color. A color with blue set to 0 indicates the absence of color and emits no blue light. Blue-Specifies the intensity of blue as an integer from and including 0 to255.A color with green set to 255 will appear bright green, or fully saturated with color. A color with green set to 0 indicates the absence of color and emits no green light. Green-Specifies the intensity of green as an integer from and including 0 to 255.A color with red set to 255 will appear bright red, or fully saturated with color. A color with red set to 0 indicates the absence of color and emits no red light. Red-Specifies the intensity of red as an integer from and including 0 to 255.In the RGB color model, the following are true: Colors can be viewed spatially using the RGB cube depicted in the following illustration: Light is emitted and displayed by the intensity at which these colors are projected by electron guns. On a cathode ray tube (CRT) screen, each pixel (picture element) consists of a triad of phosphor colors: red, green, and blue. RGB is a color model based on additive primary colors. There are two color models available: RGB and HSV. ![]()
