DESCRIPTION

       glutGetColor retrieves a red, green, or blue component for
       a given color index colormap entry for  the  current  win-
       dow'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. glut-
       GetColor 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 glutGet(GLUT_WINDOW_COL-
       ORMAP_SIZE),  that is if the color index is transparent or
       outside the valid range of color indices.
