Somewhat nearer a reddish pink? (4)
I believe the answer is:
rare
'pink?' is the definition.
(eg a rare steak might be pink)
'somewhat nearer a reddish' is the wordplay.
'somewhat' indicates the answer is hidden within the clue.
'RARE' is hidden within 'nearer a reddish'.
(Other definitions for rare that I've seen before include "Might a four-leaf clover be so" , "Very infrequent, lightly cooked" , "difficult to find?" , "Excellent; uncommon" , "Scarcely seen" .)
