Crossword Genius

Colour of bird down (7,4)

Ross

I believe the answer is:

peacock blue

'colour' is the definition.
(peacock blue is a kind of colour)

'bird down' is the wordplay.
'bird' becomes 'peacock' (peacock is a kind of bird).
'down' becomes 'blue' (I've seen this before**).
'peacock'+'blue'='PEACOCK-BLUE'

'of' is the link.

(Another definition for peacock blue that I've seen is " Colour".)

I've seen this clue in The Times.
