This should work with the standard pointer.

Hint - 0x00FF00 looks like a 24 bit colour (green). If this comes out
yellow then you are probably running a 16 bit screen mode. Perhaps you
are also trying to use 0xFF00FF as the mask color?

makecol(0x00,0xff,0x00)  will produce green in the current screen mode
makecol(0xff,0x00,0xff)  or bitmap_mask_color(screen) will produce the
correct mask color
