In an interview with The Metro, Gaiman said: "I figure that anything Stephen Moffat has revealed about my episode, I am also at liberty to reveal in public."
He then joked: “He said that it’s going to be on television and that it will be in colour.”
The Gaiman-written story will form part of Matt Smith's second series as the Doctor and is expected to air in early 2011. The writer previously revealed to BBC News that his instalment had the working title, 'The House of Nothing'.
The next episode in the current series, 'Vincent and the Doctor' - written by Richard Curtis - airs this Saturday at 6.40pm on BBC One.
