glutGetColor(3GLUT)                                 GLUT                                 glutGetColor(3GLUT)



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 glutGet(GLUT_WINDOW_COLORMAP_SIZE), that is if the color
       index is transparent or outside the valid range of color indices.
