Understanding Color Models and Spot Color Systems  A color model
is a system for creating a full range of colours from a small
set of primary colors. There are two types of colour models:
additive and subtractive. Additive color models use light to
display color, while subtractive color models use printing inks.
The most common color models that graphic designers work with

computer monitors and it’s also used in digital photography.
Cathode ray tube, LCD, plasma and LED displays all utilize the
RGB model.    In ord
