CMYK is a color model based on four primary colors: cyan, magenta specific (blue-green),
yellow and key (black). Sometimes pronounced "C-Mike," CMYK can also be written as YMCK or CYM. The four colors in the CMYK color system can be combined in different ways to create other secondary colors.
Using the printing of color photographs, this subtractive color model works by causing the color of an object through which
light is not absorbed. For example,
lettuce is green because it absorbs all colors except the
cyan and yellow, the two colors that combine to produce the secondary color the eye sees as
"green."Although not considered a black primary color in most systems, color, which is included in the CMYK color model, because the combination of the three primary colors is a clear brown, rather than a true black. Therefore, "key" was added to the system as black, which is characteristic of the "contact plate," the standard plate is inked with black only.
RGB (red, green, blue) is an alternative to CMYK color model. The system selects a photographer will depend on the true colors that you want to visit the impressions that result. For example, if an RGB system can be a "pure" blue (which is 100 percent blue), CMYK tends to produce more violet blue. The color that is most appropriate depends on the object and the eye of the photographer.
