Purity of a color and is the proportion of gray component in a hue,
represent from 0% to 100% (pure color).
Value is the relative lightness and darkness of a color, usually measur from 0% (black) to 100% (white). RGB mode Saturation refers to
RGB mode is bas on the principle of mixing the three primary colors in nature. The three primary colors – r (R), green (G) and blue (B) – are divid into each color according to the brightness value from 0 (black) to 255 (white).
Assign in order, thereby indicating its color
When the primary colors of different brightness are mix, 256 * 256 * 256 colors are form, which is about 16.7 million malta number data kinds. For example, bright r can have an R value of 246, a G value of 20 and a B value of 50. When the brightness values of the three primary colors are equal, gray is produc.
When all the brightness values are 255
Pure white is produc; and when all the brightness values are 0, pure black is produc. When the three kinds of color light fairy tales of security: technological arrest are mix, usually the color generat is brighter than the original color brightness value, so the color generation method in RGB mode is also call the color light addition method.
Saturation refers to color matching digital printing
3. CMYK mode Saturation refers to
CMYK color mode is a printing mode. The four letters stand for Cyan, Magenta, Yellow and Black, which represent the four ink colors in printing. CMYK mode is basically the same as RGB mode, but the color generation principle is central african leads different. In RGB mode, the color light emitt by the light source is mix to create color, while in CMYK mode, different proportions of C, M, Y, K black ink on paper, after absorbing part of the spectrum, the reflect light entering the human eye produces color. When C, M, Y and K are mix into colors, as the four components of C, M, Y and K increase, the light reflect to the human eye becomes less and less, and the brightness of the light becomes lower and lower, so the color production method in CMYK mode is also known as the color light subtraction method.
