Color theory

What is RGB color?
Red, green, and blue light can be added together in various amounts to produce a large range of colors
observed in nature. For example, red and green can be combined to create yellow. Televisions and computer
monitors create colors in this manner. RGB color is a method of describing colors by indicating the amount of
red, green, or blue needed to produce a certain color.
What is CMYK color?
Cyan, magenta, yellow, and black inks or toners can be printed in various amounts to produce a large range of
colors observed in nature. For example, cyan and yellow can be combined to create green. Printing presses,
inkjet printers, and color printhead LED printers create colors in this manner. CMYK color is a method of
describing colors by indicating the amount of cyan, magenta, yellow, and black needed to reproduce a particular
color.
How is color specified in a document to be printed?
