Had a few comments about the colouring of some of the vintage Doctor Who Target books. With one or two exceptions, I haven't used any colour photographs on these designs. They are coloured in Photoshop.
I don't make any claim that the colours are correct. I understand that the Drahvins' costumes (from Doctor Who and the Chumblies) are a pale blue/grey and not pale green - but I think they look better as green.
I do, however, stand by the colouring of Mavic Chen on Doctor Who and the Time Destructors cover though. His skin had a rather thick orange pallor whilst he wore a pale blue roll-neck under his white apron! That's something I've always been aware of since a kid. I vaguely recall seeing a colour picture many many years ago.
Here are deconstructions of three of my favourite designs showing the original photographs from which the final covers were made.
