Matching Walthers latest Milwaukee Road yellow cars

Does anyone know what PollyS paint mixes match the shade of Armour yellow that

Walthers used on the new cars they are now offering ? PollyS Armour Yellow is too

dark by itself.Maybe someone has done an expensive test by buying a few colors

and mixing them.I have a few undecorated cars and would like them to eventually

match as close as humanly posssible. I have been trying to match their NYC light

and dark greys too. Still working on that one but adding black and white to SP

Lark Dark Gray is very good but never got to write down the ratio of added colors

so I couldn’t tell how much to add. I take a swatch paint example on a white

piece of plastic and let dry to see which is closest but not sure this is effect use of

time and materials.Any help would be apprecitated.

Why not send an email to Walthers and ask them?
