Another Mk.I Canadian colour question

[Ron Pier]

That's exactly what I would do Rick. By using half dozen jam jars with measures on the outside with felt pen, and adding green and or brown until you have the desired shade with recorded information for your final mix. Usually all the jars can be added back into a 5 litre can without any adverse effect to the final colour. I've done it loads of times, and would undoubtedly find it easier to do than explain it. Ron
