She’s greyish and may turn paler (5)
I believe the answer is:
pearl
'she's' is the definition.
'turn paler' is the wordplay.
'turn' is an anagram indicator.
'paler' is an anagram of 'PEARL'.
'greyish and may' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for pearl that I've seen before include "Gem; an attacked Harbor" , "Much loved and valued person" , "See 12" , "finest example" , "Precious stone from shellfish" .)
