Adventures of Superman (Syndicated, 1952-58). The show’s first two seasons (episodes 1–52, 26 titles per season) were filmed in black-and-white; seasons three through six (episodes 53–104,
13 titles per season) were filmed in color but originally telecast monochromatically in first-run syndication. Television viewers would not see Superman in color until the series was syndicated to local stations in 1965. (Wikipedia)

Loved this when I was a kid, watching it in reruns. Been rewatching the series on MeTV and am a little stunned by how kid-oriented the show actually was! Still a hoot to watch, though.
