3. Color model
– A color model is an orderly system for creating a whole range of colors from a
small set of primary colors. There are two types of color models, those that are
subtractive and those that are additive.
4. Types
– RGB Color model
– CMYK Color model
– HSV Color model
– YIQ color models
5. RGB Color Model
There are two basic kinds of color models, additive and subtractive. Let's look at
an additive color model first. The most common one is Red/Green/Blue, usually
referred to as RGB.
6. CMYK Color Model:
– The most common subtractive color model is Cyan/Magenta/Yellow/Black,
usually referred to as CMYK. It is what printers use, and you will sometimes also
see it called process color because it is used in the four color printing process.
7. HSV Color Model
– HSV Color Model Hue, Saturation, Value or HSV is a color model that describes
colors in terms of their shade (saturation) and their brightness (value). HSV
color model is based on polar coordinates.
8. YIQ color models
– YIQ is the color model used for color TV in America.(NTSC = National Television Systems
Committee). Y is luminance I & Q are color (I = red/green, Q = blue/yellow).
9. APPLICATIONS
• There are wide application of color models
• RGB Color model used in computer graphics image processing, image analysis,
and in image storage.
• CMY model used in printing.
• HSV and HSL used in human visual perceptions, computer graphics processing,
• Computer vision, face recognition, image analysis, image design ,image editing
software’s, video editors etc.
• YIQ color models are used in television broadcasting systems and video
systems.
10. Remarks
– A color model is a system that uses three primary colors to create a larger range of
colors. There are different kinds of color models used for different purposes, and each
has a slightly different range of colors they can produce.
