Hello out there,

  I have some problems which are concerning colors display in X-window system.
  I am trying to display more than 256 different colors, however, everytime
  when I used up the available color cells (256), I will obtain some (junky)
  color.  I am wondering if there is a way that I can create another color
  map to display 256+ colors.  

  I used XAllocColor to allocate the color cells.

  I have tried to use XCopyColormapAndFree() function (Xlib). But it does not
  seem to work.
  The following is the configuration on my system under X..


  Class : PseudoColor
  Depth : 8 planes
  size of colormap : 256 entries
  red, green, blue mask : 0x0, 0x0, 0x0
  significant bits in color speci. : 8 bits. (I think it is the problem)


  Please Send me mail at
