[mapserver-dev] bug in mapscript colorObj ?

I try to set transparent color to REFERENCE map, so that the box is
According to documentation, i use -1 for indication, that the color
should be transparent
color = mapscript.colorObj(-1,-1,-1)
but this seems to be understood as invalid color, according to
#define MS_VALID_COLOR(color) (((color).red==-1 || (color).green==-1 ||
and the box is filled with red color (default value)
When I use -255 for the colors triplet, it is converted to positive
integer (and so the box is black).
When I tried to set alpha directly
color.alpha = 0
It did not help
Any hint what to do? Is that a bug in mapserver/mapscript ?
P.S. Sorry for cross posting, not sure, where to find the right answer.
