I've always been impressed with the vivid colors in evidence on STAR TREK: The Original Series. We know that the network (NBC) wanted it that way to help sell RCA Color TVs. As I looked at last night's episode that aired on MeTV, I think I could nominate "The Apple" as perhaps the most colorful episode. The opening scene features a mix of red, blue, yellow and green shirted crewpersons beaming down to a planet with bright green vegetation, colorful flowers, and a red sky. That looked great even on the crappy CRT's of the day.
