Peter, volume 10, number three (that's the September 2006 issue aka the 2007 Narrow Gauge Annual) of Finescale has a chapter devoted to caboose 0526, complete with color photos (p 63). I don't know if this applies. Looks kinda like a medium dark red to me. Chinese Red, I think, is more orangey. I will plow through some more Finescales, as I recall there being another, "Everything you wanted to know about D&RGW cabooses, but were afraid to ask") article in one of them.
