Right up until the late 1960s, Britain's television sets still flickered black and white.
Then in the summer of 1967, the pioneers at BBC2 changed everything and they started to broadcast in colour. Britain's front rooms were transformed, as were the worlds of fashion, advertising and magazines.
Inspired by this explosion of colour in popular culture, Colorplan took a pioneering step of its own and began to assemble a paper range of a scope and scale that was - up to that point - simply unheard of.
Over the next five years, this remarkable range was carefully, skilfully and methodically assembled.
Never before had a paper range offered such a broad range of colours in every weight,size and finish.
