The Cube 2 was an ident used by BBC Two between 2 December 1967 and 28 December 1974. It featured a stylised "2" that rotated on screen. Launch In 1967, BBC2 was the first UK television station to launch a full colour service on the UHF frequency band, and to mark the occasion a new symbol was launched. However, there is some confusion as to when the symbol was actually launched. Some colour programming was shown in the early part of the year, before the official date of 1 July 1967, but even the official launch date was only in the main regions. 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. Components of the look The ident was originally a cube with a "2" on each face, each a different colour. The ident would start by three light spots of red, green and blue, the three primary colours for television. These light spots then merge to form a white spot. Around this spot, a blue numeral "2" would form up by drawing it. The "COLOUR" legend would then appear below the 2, and the 2 would begin rotating to reveal other colour 2's, in the order blue, red, green and white. This ident would continue to rotate against the black background. The ident was formed by an animated startup and a film of a mechanical model, with the whole thing being played off a recording. The ident was modified in early 1972 when both channels presentation were brought into line. The cubed "2" was changed so all the colours were cyan blue, with the "2" now spinning above a line with an italic "COLOUR" legend. A variety of versions were used around this period: the first being a blue 2 over a black background with white line and caption. Another version included the same as before, but with a dark blue background instead of a black one. The final version included a slightly lighter background colour and a cyan line and caption. The black background version was first to be used, which then made way for the dark blue background, with the cyan version last used, however this order is disputed. These idents were mechanical, and filmed live as required from the BBC2 NODD room and
