I'll have to agree with Ron Rudnick. The DSP&P Tiffany Reefers were originally white. I did extensive research on the one remaining Tiffany car that was near the C&S Leadville Roundhouse. I scrapped through the various layers of paint and reported these findings in the DSP&P Historical Society magazine The Bogies & The Loop (issues 53 and 54 Oct. 2012 and Jan. 2014). There is some evidence that these reefers were repainted when they were relettered and renumbered during the 1885 Union Pacific System renumbering. However, the "jury is still out" as far as exact colors as the lone Tiffany at Leadville was used as a shed and was painted boxcar red at the time. Paint chips indicated layers of white (crème), yellow and boxcar red and research shows that the car was probably placed on the ground sometime before 1903, as it retained link and pin couplers. It should be noted that historian Dave Wilke has determined that the Tiffany Reefers of the Lehigh Valley were painted a pale green, much like the color that Randy Hees discussed.
