Try this code:

def_transparent_rgb(tr_lgrey, 0.73, 0.71, 0.75);

def a_u_lgrey(expr P) =
   T:=identity;
   thfill P withtransparentcolor tr_lgrey;
enddef;

There are a few predefined transparent colors, the most interesting of
them is tr_bg (current scrap background). Standard opacity value
(defined in the layout section) is applied.
