Consider this sequence of calls glColor3f 00 10 00 glColor3f
     Consider this sequence of calls:  glColor3f (0.0, 1.0, 0.0);  glColor3f(1.0, 0.0, 0.0);  glVertcx2i (1, 1);  glVertex2i (2, 2,2);  What color is the vertex (1, 1. 1)? What color is the vertex (2, 2, 2)?  
  
  Solution
glColor3f(0.0,1.0,0.0);
 This will set the color to green
 glColor3f(1.0,0.0,0.0);
 This will set the color to red.
 glVertex2i(1,1);
 recently color is set to Red. So this will be displayed in RED color
 glVertex2i(2,2,2);
 This also displayed in RED color
