Bream colour? (5)
I believe the answer is:
amber
'bream colour?' is the definition.
'amber' can be an answer for 'colour?' (amber is a kind of colour). I'm unsure of the 'bream' bit.
'bream colour?' is the wordplay.
'colour?' indicates anagramming the letters (I've seen 'coloured' mean this).
'bream' is an anagram of 'AMBER'.
Can you help me to learn more?
(Other definitions for amber that I've seen before include "Honey-yellow colour" , "Stone" , "Name of female" , "Yellow, translucent fossil resin" , "Traffic light colour" .)
