Blue tie turned up (7)
I believe the answer is:
skyward
'up' is the definition.
('skyward' can be similar in meaning to 'up')
'blue tie turned' is the wordplay.
'blue' becomes 'sky' (I've seen this in other clues).
'tie' becomes 'draw' ('draw' can be a synonym of 'tie').
'turned' is a reversal indicator.
'draw' written backwards gives 'ward'.
'sky'+'ward'='SKYWARD'
(Other definitions for skyward that I've seen before include "Up to the heavens" , "from the ground?" .)
