lasted as long as necessary, although the ident would usually stop spinning after a while. The colour was added electronically through the NODD process used on the BBC1 ident at the time. Two clocks accompanied the look: the first lasted as long as the original ident and the second accompanied the mechanical idents. The first was a modified version of the last time-piece and featured to the right of the screen, a large clock face with markers at every minute mark and with Roman numerals for every five minutes. To the left, the BBC2 logo, with the legend "COLOUR" underneath and below that, usually programme information. The second clock featured a clockface in the centre of the screen with the number markers being replaced by a set of double lines that got progressively thicker the further round the clock face. The line, with the legend 'BBC2 COLOUR', now featuring the updated rounded BBC logo, was cyan in colour and located below the clock face. The clock design was identical to that used by BBC1, except for colour. Promotions at this point were not uniform and changed depending on requirements and time of year. 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. Special idents Christmas 1967-1970 - Christmas idents were not used during this period, but Christmas slides were produced, including the cube 2 on the left of the screen (above the logo and the word "Colour") with a Christmas tree or a snowflake on the right. Christmas 1971 - The cube 2 with coloured swirls emanating from the centre, with the font reading "Christmas" underneath. Christmas 1972 - The cube 2 with tinsel around the edges of the screen, with the font reading "Christmas in Colour" underneath. Christmas 1973 - Possibly the same version as the following year; no footage exists, only photos. Christmas 1974 - The cube 2 with all sides orange rotating and decorated with stars and a bauble where the dot usually sits; the font underneath read either "Christmas Eve", "Christmas Day" or "Boxing Day", depending on the day. Due to lack of video recordings from this era, and due to the common broadcasting practice of wiping old tapes for reuse, very few examples survive of this
