NAME
       glutGetColor - retrieves a red, green, or blue component for a given color index colormap entry for the layer in use's logical colormap for
       the current window.

SYNTAX
       #include <GLUT/glut.h>

       GLfloat glutGetColor(int cell, int component);

ARGUMENTS
       cell	 Color cell index (starting at zero).

       component One of GLUT_RED, GLUT_GREEN, or GLUT_BLUE.

DESCRIPTION
       glutGetColor retrieves a red, green, or blue component for a given color index colormap entry for the current  window's	logical  colormap.
       The  current  window  should be a color index window. cell should be zero or greater and less than the total number of colormap entries for
       the window. For valid color indices, the value returned is a floating point value between 0.0 and 1.0 inclusive. glutGetColor  will  return
       -1.0  if  the  color  index specified is an overlay's transparent index, less than zero, or greater or equal to the value returned by glut-
       Get(GLUT_WINDOW_COLORMAP_SIZE), that is if the color index is transparent or outside the valid range of color indices.
