English fan wearing bright colour is given snub (8)
I believe the answer is:
rebuffed
'given snub' is the definition.
(to rebuff someone is to snub them)
'english fan wearing bright colour' is the wordplay.
'english' becomes 'E' (abbreviation as in OED).
'fan' becomes 'buff' (synonyms).
'wearing' indicates putting letters inside.
'bright colour' becomes 'red' (red can be a bright colour).
'e'+'buff'='ebuff'
'ebuff' put within 'red' is 'REBUFFED'.
'is' is the link.
(Other definitions for rebuffed that I've seen before include "Cold-shouldered" , "Snubbed, slighted" , "Rejected ungraciously" , "Snubbed, rejected unkindly" , "Rejected outright and bluntly" .)
