There are four main types of color: additive, primary, secondary, and pigment. Color can also be described using various color models including RGB, CMYK, HSB, and LAB. RGB uses red, green, and blue phosphors; CMYK uses cyan, magenta, yellow, and black inks; and HSB describes hue, saturation, and brightness. Web colors are specified using a six-digit hexadecimal code representing RGB values. Additional resources for learning about color are provided.

2.  There are 4 types of colors Additive, Primary, Secondary, and
Pigment.
 Additive- A computer monitor uses three phosphors that
appear as red, green, and blue when activated. Other colors

 Secondary- Cyan, Magenta, and Yellow are the Secondary
Colors.
 Pigment- Reflected light, when a pigment absorbs certain
light, wavelengths, and reflects others.

3.  There are many abbreviations for color.
 HSB, RGB, CMYK, and LAB.
 HSB- Hue, Saturation, and Brightness
 RGB- Red, Green, Blue
 CMYK- Cyan, Magenta, Yellow, and Black
 LAB- L= the lightness component that can range
from 0-100
A= The green-red axis
B= The blue- yellow axis. Both range from +128 to -128

4.  Web Color- a 6 digital number is the

 Custom- allows you to work matching
color systems such as Pantone.

5.  Hue- the color’s name such as blue,
orange, red, etc. it is located on the
color wheel expressed as a degree
between 0-360
