Specifying colors
To specify colors, Common Graphics defines the following class: 
CgRGBColor 
Specifies a color using integer values in the range 0-65535 giving the intensities of the color primaries red, green, and blue. 
There are three ways to create a CgRGBColor in Common Graphics as follows: 
•Specify the red, green, and blue intensities of the color with integers between 0 (full off) to 65535 (full on). 
•Specify a color name to look up in a database of colors. 
•Specify the RGB intensities in string form.
