Colour of a lovebird, variegated (5,4)
I believe the answer is:
olive drab
'colour' is the definition.
(I know that olive drab is a type of olive)
'a lovebird variegated' is the wordplay.
'variegated' is an anagram indicator.
'a'+'lovebird'='alovebird'
'alovebird' anagrammed gives 'OLIVE-DRAB'.
'of' is the link.
(Other definitions for olive drab that I've seen before include "Mil. uniform colour" , "Colour of some military uniforms" , "Military uniform colour" , "a shade unsparkling, maybe" , "Greyish" .)
