Homebrew PCBs

Here's a comparison shot.  On the left is an original 1974-vintage Mark-8
board.  On the left is the closest 'natural green' PCB material I could find
thus far.  They're not impossibly far off, but there is I think more of a
bluish hue to the Mark-8 board.  I'm wondering, could I dye my modern stock
to look like the Mark-8?  Or does anyone make something similar to that
color now?
