Color vs B&W
Personally I prefer the B&W seasons. It just seemed "dirtier" I suppose. Watching the color episodes the feel is completely different...everyone seems so clean and colorful!
For me, B&W helped give the impression that everyone was dirty and dusty...which I imagine would be accurate. Driving a wagon across the prairie was not the cleanest job y'know...and water was likely more valuable than gold, so one could surmise bathing wasn't a regular thing on the wagon train.
For example, the female cast members' makeup is much more vivid in the color episodes, which for me gives the production what I call "the studio look". Now the Anne Blythe episode with Ronald Reagan...she had a lot of free time on her hands and may have had the opportunity and resources to give herself a makeover. But the typical females on a wagon train...? It would be a lot less likely. I've always thought it was amusing when a prairie woman is wearing very noticeable false eyelashes...😀
