Ah, and fortunately for those of you not under Donald Trump's 
jurisdiction, this version also works:

#macro DotGrey (Colour)
   #local C = colour Colour;
   (0.2126 * C.red + 0.7152 * C.green + 0.0722 * C.blue) // ITU-R BT.709
#end

We have fantastic spelling.  We have tremendous spelling.  You won't 
believe how good our spelling is.  Let me tell ya, no country does

winning with our spelling.
