GTW Paint Colors

[GTW6401]

Hi all,

    I need to know the paint colors used on all Grand Trunk Western locomotives. I know they are close to Conrail Blue and SP Daylight Red or SP Scarlet but thats just a guesstimate. My question is if this is as good as I am going to get or who I should contact (such as Aristo-Craft as they make a GTW GP-40) about what colors to use to custom paint locomotives?
