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 glutGet(GLUT_WINDOW_COLORMAP_SIZE), that is if the color index is transparent or outside the valid range of color indices. <A NAME="lbAF"> </A> <H2>SEE ALSO</H2> glutGet, glutSetColor, glutCopyColormap <A NAME="lbAG"> </A> <H2>AUTHOR</H2> Mark J.
