Printing and computer color

Remember that in printing, process colors: yellow, cyan (bright blue), magenta (blue red), and black make up all other colors.

If you select a color from a color swatch book and ask 1,000 printers to reproduce that color, you'll get 1,000 different colors.
The color of the paper affects the color of the ink.

Know that on computer or television screens, red, green, and blue make up all other colors.

Colors viewed on monitors, computer or television will vary significantly unless calibrated.
