Colour in character in comic (6)
I believe the answer is:
tintin
'character in comic' is the definition.
'tintin' can be an answer for 'character' (I have seen 'Comic character' mean 'tintin' so perhaps 'character' could also mean 'tintin'). I am not sure about the 'in comic' bit.
'colour in' is the wordplay.
'colour' becomes 'tint' (tint is a kind of colour).
'tint'+'in'='TINTIN'
Can you help me to learn more?
(Other definitions for tintin that I've seen before include "Herge's cartoon hero" , "Herge's adventurer" , "Herge's adventurous young Belgian reporter" , "cartoon character" , "Comic character" .)
