On further investigation, it looks like the fill on the truetype symbol 
is white but the symbol is drawn in black, the requested color. The 
layer looks like:


   #  Building
   LAYER
     NAME "buildin_p"
     GROUP "CO"
     STATUS DEFAULT
     MAXSCALE 100100
     TILEINDEX "tindex-50k"
     DATA "buildin_p"
     TYPE POINT
     CLASSITEM "ATC"
     CLASS
       ...
     END
     ...
     CLASS
       EXPRESSION "177" # Industrial building
       STYLE
         SYMBOL "building"
         SIZE 15
         ANGLEITEM "ANGLE"
         COLOR 0 0 0
       END
     END
   END
