D&RGW Reefer Colors...

We're in the process of repainting Denver & Rio Grande Western forty foot reefer number 168 at the the Sumpter Valley, and I have a few questions. First off, does anyone have any in service pictures of the car? Second, the final paintjob seems to have been yellow sides,red ends, roof, and trucks, black hardware and flying Rio Grande lettering. But, as I've been scraping paint, I've also found orange down deep. So, is it possible the 168 wore the orange paintjob, and if so, what color should the ends and undercarriage be? Also, since the orange is early on, I'm guessing D&RGW lettering instead of the flying?

Anyway, if anyone can help out on this it would be very appreciated as I would like to purchase the paint tomorrow if possible.

Thanks in Advance, Taylor
