Colorado Midland locomotive question(also DL&G)

I am working on a big painting of the crossover at Bath(Trout Creek Pass), Colorado. I am doing tenwheeler #25 with a passenger train, with a DL&G train under it. I am fortunate to have Cafky's book on the CM .Some painters showed red headlight boxes after 1890. The lettering on the tender (with the big herald and C.M on either side) looks like gold[leaf] paint with red or green shadowboxing. Any educated opinions out there? As for the DL&G, #57 was the last Mason Bogie on the property. Can we assume it was running in the mid-1890s? I know I do a lot of fishing for facts here, but this is a great source for such information. Thanks in advance!
