Ask the X server (you can't always change the color map).

X has functions for that:

# man BlackPixel
...
       BlackPixel(display, screen_number)

       WhitePixel(display, screen_number)
...
       The BlackPixel macro returns the black pixel value for the specified screen.

       The WhitePixel macro returns the white pixel value for the specified screen.
