Colour of two wines (4-3)
I believe the answer is:
rose-red
'colour' is the definition.
(I've seen this before)
'two wines' is the wordplay.
'two wines' means two replacements for 'wine'.
'wine' becomes 'rose' (rose wine is a kind of wine).
'wine' becomes 'red' (red is a type of wine).
'rose'+'red'='ROSE-RED'
'of' is the link.
(Other definitions for rose-red that I've seen before include "A -- city, half as old as time" , "Coloured like a flower" , "Colour (of Burgon's city)" .)
