Matching Atlas Paint color

[Anonymous]

Does anyone know what paint color matches the yellow Atlas used on their AC&Y H15-44 locomotive. The Akron Canton & Youngstown Historical scociety web page lists UP Yellow as the prototype color. I have the #200 Atlas loco and would like to get one of their undecorated H16s and paint it to match. The AC&Y web site sells the decals to number them, so thats not a problem. But would like to get the color to closely match.

Thanks for any help[:)] Gregg
