First UK TV Series to be Filmed in Colour

The first UK TV series to be filmed entirely in colour was Stingray in 1964.

There had been colour programmes produced in the UK prior to this but not a whole series.

In 1956/7 a series called The Adventures of Sir Lancelot were initially filmed in black & white but then they changed to colour for export to the USA.

It should be noted that colour transmission didn’t start in the UK until 1967.
