Colourful English Times involved in hearing (6)
I believe the answer is:
exotic
'colourful' is the definition.
(I've seen this before)
'english times involved in hearing' is the wordplay.
'english' becomes 'E' (abbreviation).
'times' becomes 'x' (2 times 4 is 2 x 4).
'involved in hearing' becomes 'otic' (otic means relating to the ears).
'e'+'x'+'otic'='EXOTIC'
(Other definitions for exotic that I've seen before include "Foreign, strange or exciting" , "From a foreign place" , "Having a strange beauty" , "Interestingly different or strange" , "type of dancer?" .)
