Color matching the Thomas Line.

[Artist794]

I'm looking to do some body work on some of my Thomas models, currently transforming a scrap Thomas into the Day out with Thomas dummy in HO scale. I wanted to see if anyone knows of a brand or mixture of paints that will be a close match to the stock Blue, Reds, Greens, etc. that Bachmann uses in the Thomas line. Anything information would be very helpful.
