Unfortunately not as simple as I had hoped.
Now, given :

	\let \Font = \font
	\def \font #1= #2 at #3 pt
		{
			\message {Loading font \string #1 = #2 at #3 pt}
			\expandafter \Font \csname font:\string #1\endcsname = #2 at #3 pt \relax
			\edef #1{\csname font:\string #1\endcsname \special {color cmyk 0 0 0 1}}
		}

(i.ẹ, initially mapping all fonts to black)

I get

(repeated many many times).
