I don't remember where but I think I have readed about my current problem
somewhere on this newsserver. Currently I can't find it so I report it. I'm
affraid it could be expected behaviour but I can't find any note about it in
documentation.

#macro Test(Radius)
  sphere{0,Radius}
#end

#local Float=1;
#local Point=<2,3,4>;
#local Color=color rgb <5,6,7,8,9>;

Test(Float)          // works
Test(Point.x)        // works
Test(Color.red)      // not
Test(0+Color.red)    // works
