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.

glutGetColor
	glutGetColor(ndx, component) -> None

GLfloat glutGetColor(int cell, int component);

cell      Color cell index (starting at zero).

component One of GLUT_RED, GLUT_GREEN, or GLUT_BLUE.

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.
