Concept 1.2: Specifying a Color
================================

Idea:
=====
Concept1.5 in Chapter 1 let us change a object's
color.  Here we examine the details.

Whenever an object is drawn it is drawn with the
the currently specified coloring scheme.  In general 
you should set the color first before drawing the object. 

To set a color, use the command glColor3f().  It takes 
three parameters, all of which are floating point
numbers between 0.0 and 1.0.  The parameters are in 
order red, green and blue components of the color.  
Here are eight commands and the colors they would 
specify:

=====================================================
Command				Set's Color To
=====================================================

glColor3f(0.0, 0.0, 0.0)	black
glColor3f(1.0, 0.0, 0.0);	red
glColor3f(0.0, 1.0, 0.0)	green
glColor3f(1.0, 1.0, 0.0);	yellow
glColor3f(0.0, 0.0, 1.0)	blue
glColor3f(1.0, 0.0, 1.0);	magenta
glColor3f(0.0, 1.0, 1.0)	cyan
glColor3f(1.0, 1.0, 1.0);	white
