Opps, didn't notice it wants XColors.  You can just make those yourself,

XColor white, black;
while.green = white.blue = white.red = 0xffff;  /* always 16-bit... */
black.green = black.blue = black.red = 0;

I don't think the pixel value matters, from the XRecolorCursor manpage:

       The XRecolorCursor function changes the color of the spec-
       ified cursor, and if the cursor is being displayed on a
       screen, the change is visible immediately.  The pixel mem-
       bers of the XColor structures are ignored; only the RGB
       values are used.

I assume the same applies to the colors used when making the cursor.

You're right, my mistake.
