Color Models In Digital Art Software
RGB Color Model
This color model is used mainly to display color on a monitor such as a computer or television. What does the RGB stand for? It stands for the three primary colors used in the model; Red, Green and Blue. Mixing these colors together in different strengths results in other colors; 16,800,000 colors in fact. When you add red, green and blue together at 100% strength each, you get the color white.

CMYK Color Model
This color model is used for print related projects. The letters stand for Cyan, Magenta, Yellow and Black. When you mix these colors together at 100% strength, you get the color black.

Grayscale Color Model
What happens when you mix black and white? You get gray! Well, you can really get several different shades of gray depending on the amount of black and white you use. There are 256 shades of gray in the Grayscale Color Model. Think of these shades of gray along a straight line with black (numeric value of 0) at on end and white (numeric value of 255) at the other end. All the shades of gray will fall between 0 and 255.
HSB Color Model
This last color model discribes color in three ways; Hue, Saturation and Brightness.
Hue is another name for color. When we think of the color red, we really mean the red hue. Above is an example of a spectrum of many hues or colors that all have the same brightness and saturation.
This is a way to describe variations of one color. Saturation is the variation of intensity of a color. The more saturated a color; the more pure the color is said to be.
This is another way to describe variations of one color; from light to dark. In the image above, you can see that blue ranges from light to dark blue.
