White - he was Colonel White, which I suppose if you are being picky is actually the absence of colour - but that was his designated name. Have you noticed the similarity between CS and footie pundit Alan Hansen?
No, no, no, no, no Andy! You've just spoilt a beautiful dream! I've always loved Captain Scarlet and now you have gone and tainted my dreams by saying he looks like the awful Alan Hansen! I'm crushed.
Actually Captain Scarlet(Paul Metcalfe[his real character name]) was based on Cary Grant, but he was voiced by Francis Matthews. Gerry Anderson has just announced a new series of 26 episodes of CS, which should come out in 2005. These will be produced using 'Hypermarianation', which is a form of computer generated imagery. The plot will be more or less the same, but Cloudbase will be bigger, there will be 12 Angels instead of 5 and Lt. Green will be female.
