Colour makes church ascend (6)
I believe the answer is:
cerise
'colour' is the definition.
(cerise is a kind of colour)
'church ascend' is the wordplay.
'church' becomes 'ce' (abbreviation for Church of England).
'ascend' becomes 'rise' (rising is a kind of ascending).
'ce'+'rise'='CERISE'
'makes' acts as a link.
(Other definitions for cerise that I've seen before include "Shade of red" , "Vivid reddish-pink" , "Bright cherry-red colour" , "Reddish-pink colour" , "Light clear red" .)
