The colors of the RGB color model can be mixed to produce the cyan, magenta, and yellow of the CMY
color model and vice versa. Two colors of one model are mixed to produce the color of the other model
(mixing blue and green produces cyan, for example). The remaining color is the complement of the
color produced (red in this example). Complementary colors are: red and cyan, green and magenta, blue
and yellow.
Printed Color
The printer produces full-color output using four toner colors: cyan, magenta, yellow, and black. These
four colors make up the CMYK color model.
Note
❒ Mixing CMY in equal proportions should hypothetically produce pure black, but imperfections in the
ink cause an equal measure of these colors to produce a muddy or dark brown. Black toner is added
to the color model in order to make it possible to produce pure black.
For example, if the image is created with cyan only, there is no problem in printing all of it with cyan
toner. However, full-color images are actually comprised of 10,000s of fine colors. These fine colors
can be expressed by changing the ratio of CMYK toner particles to be printed per unit surface.
There are also dark and light shadings to each color. These shadings can be expressed by changing the
amount of toner particles to be printed per unit surface.
