Actually, many people then were getting color TVs. The reason the sets on ST:TOS were so colorful was to attract viewers who had spent a bunch of money for a new color TV set, and wanted to see things in vivid colors. The modern HD scans of the original film look fantastic. They do, however, show how low-budget the sets were, but the detail of the original film is quite amazing, and these old shows look far better than most stuff produced in the 1990s which was done using videotape.
