Love selection of fruit (6)
I believe the answer is:
Here is my best explanation:
'fruit' is the definition.
(orange is a kind of fruit)
'love selection' is the subsidiary indication.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'selection' becomes 'range' (I've seen this before).
'of' is the link.
(Other definitions for orange that I've seen before include "Belisha beacon colour", "Colour of an onager?", "divided internally, naturally", "African flower", "Royal house - fruit - colour", "Fruit; pigment", "Go earn the fruit", "shade", "Loyalist colour" and "A rainbow colour".)
