Some brash entertainment makes you pale (5)
I believe the answer is:
ashen
'pale' is the definition.
(synonyms)
'some brash entertainment' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'ASHEN' is hidden in the letters of 'brash entertainment'.
'makes you' is the link.
(Other definitions for ashen that I've seen before include "Pale (faced)" , "White" , "Wan - wooden - pallid" , "(Of face) pale (with shock)" , "Grey-faced" .)
