It was later that year on 2 December for the full country to receive colour transmissions, and because of these different dates, it is difficult to see when this ident was introduced.
The ident would start by three light spots of red, green and blue, the three primary colours for television.
The ident was formed by an animated startup and a film of a mechanical model, with the whole thing being played off a recording.
[2][4] A variety of versions were used around this period: the first being a blue 2 over a black background with white line and caption.
[2][3][4][5] The final version included a slightly lighter background colour and a cyan line and caption.
The holding slides used for this period featured a white, "2" logo and spot located at the bottom left of the image, with a Colour legend below the 2 and programme information to the right of the 2.
