In the 1950s the BBC produced experimental colour transmissions on both 405 and 625 lines. All using NTSC adapted to suit the different systems. Several manufacturers made experimental colour sets using American CRTs and largely American technology. Marconi built cameras, nicknamed coffin cameras on account of their size and shape, using 3x image orthicon tubes.

Apparently it all worked pretty well and a lot of experience was gained. I think the decision not to start a colour service was largely financial and political rather than technical.

By 1967 when the UK colour service started there were plumbicon cameras and a well developed set of European valves and components, largely due to work by Philips.

Early sets were expensive, several thousand pounds in todays values. Roughly equivalent to the cost of 42" plasma flat screens when they first were sold.
