J. Ballard,
I'm old enough to remember when NBC color film series aired in the early 60's. Shows like Bonanza, Tales of Wells Fargo, Laramie ect. did have a red/brownish cast. I mainly point out western series as they tended to have more red/brown in scenes. Wooden structures, saloon & cabin interiors, barren ground and such. This seem to improve during the later 60's & on:
