EXAMPLE: ART102E - Apparel Design - Subtractive Mixing

Form: The cover photo for Vogue is printed using subtractive mixing, more specifically a CMYK color model. Cyan, magenta, yellow, and key black inks are printed in layers on white paper in order to create the desired colors for the photograph and words. For example, "VOGUE" is seen as red, which is caused by the subtractive color mixing process of layering magenta and yellow ink.
