I) INTRODUCTION
A color model is simply way to define color. It is also called an orderly system for creating a whole range of colors form a small set of primary colors. There are two types of color models. They are
1)subtractive color model :-It use printing inks
2)additive color model :- It use light to display color
There are several established color models used in computer graphics, but the two
most common are the RGB model (Red Green Blue ) for computer display and
the CMYK model (Cyan Magenta Yellow Black ) for printing.
CMYK Color Model
The CMYK model is used for print work and it describes colors based on their percentage of Cyan, Magenta, Yellow and Black. These four colors are used by commercial printers and bureaus and you may also find that your home printer uses these colors too. These four colors are needed to reproduce full color artwork in magazines, books and brochures. By combining Cyan, Magenta, Yellow and Black on paper in varying percentages, the illusion of lots of colors is created.
RGB Color Model
The RGB model is used when working with screen based designs. A value between 0 and 255 is assigned to each of the light colors, Red, Green and Blue. So for example, if you wanted to create a purely blue color, Red would have a value of 0, Green would have a value of 0 and Blue would have a value of 255 (pure blue). To create black, Red, Green and Blue would each have a value of 0 and to create white, each would have a value of 255. RGB is known as an “additive” model and is the opposite of the subtractive color model.
