Colin was a in-house Costume Designer for the BBC, and in 1982 he was scheduled to work on the Doctor Who story Four To Doomsday, which became the first story to be recorded following the rejection of the planned debut adventure (a replacement script was shot later).
He therefore had the task of realising the Fifth Doctor’s costume.
But one part of the Fifth Doctor’s costume that was distinctly not his idea was the retention of the question marks on the shirt lapels, first seen the year before in what was Tom Baker’s final season, designed by June Hudson.
It was a specific request from producer John Nathan-Turner, who in a memo wrote:
"I do feel that the Doctor Who shirt with the '?' mark on the lapels is worth hanging on to."He also worked on two other stories, The Power of Kroll in 1978 and The King’s Demons in 1983.
Colin later had the distinction costuming the multi-Doctor 20th anniversary story, The Five Doctors.
By default this means by head-count he provided more outfits for Doctors and recurring characters during the original run of Doctor Who than any other costumer.
Colin suffered a heart attack and died at home suddenly. His funeral is due to take place on 24th July 2012, followed by cremation.
My thoughts, and hopefully yours, are with his family.
