Colour centre in humans as an area specialized for colour vision. V2, also called the prestriate cortex, is believed to have a small role in colour processing by projecting signals from V1 to the V4-complex. Whether or not colour selective cells are present in V2 is still being investigated. Some optical imaging studies have found small clusters of red-green colour selective cells in V1 and V2, but not any blue-yellow colour selective cells. Other studies have shown that V2 is activated by colour stimuli, but not colour after images.[8] V4 also has feedback on V2, suggesting that there is a defined network
Colour recovery Colour recovery Colour recovery (or colour restoration) is a process which can restore lost colour, specifically to television programmes which were originally transmitted from colour video tape, but for which only black & white copies remain archived. Not to be confused with colourisation, colour recovery is a newer process and is fundamentally different from colourisation for several reasons. Firstly, colour recovery can only be performed if the originally transmitted colour signal can be reconstructed or recovered from some source, whereas this is not usually the case for traditional colourisation. Secondly, colourisation can be used to colourise films and programmes that
