Color - CMYK (Cyan Magenta Yellow Black Color Model)

Colors can be created in printing with color spaces based on the CMYK color model, using the subtractive primary colors of pigment:

• cyan (C),
• magenta (M),
• yellow (Y),
• and black (K).

To create a three-dimensional representation of a given color space, we can assign:

• the amount of magenta color to the representation's X axis,
• the amount of cyan to its Y axis,
• the amount of yellow to its Z axis.

The resulting 3-D space provides a unique position for every possible color that can be created by combining those three pigments.
