Primary, Secondary and Tertiary Colors
• In the RYB (or subtractive) color model, the primary
colors are red, yellow and blue
• The three secondary colors (green, orange and purple)
are created by mixing two primary colors
• Another six tertiary colors are created by mixing
primary and secondary colors

Electronic and Pigment Based Color
(CMYK) When use pigments, you add differing amounts of paint
to create color. The more pigment you add, the darker your color
usually becomes. 0% pigment is white, at 100% pigment (or you
have mixed together pigments that absorb every wavelength of
visible light) you have black.
(RGB) A LCD screen starts out black; light is added to the screen
in differing amounts to create color. The more light from the red,
green, and blue phosphors that is added, the brighter and lighter
the screen becomes. Therefore, when you have 0% intensity of
red, green, and blue the screen is black and when you have
100% intensity of the red, green, and blue phosphors, the screen
is white.
Color Properties
• Hue: The name of the color. This allows us to distinguish one color
from another by name
• Value (Saturation): The lightness or darkness of a color. The most
important to keep in mind: if the value of a color is wrong, then the
color is wrong
• Intensity: The purity or strength of a color (affected by other hues or
value)
• Tune: The darkness level of grey
