Equitable; blonde (4)
I believe the answer is:
fair
I believe this clue is a double definition.
'equitable' is the first definition.
(synonyms)
'blonde' is the second definition.
(similar in meaning)
(Other definitions for fair that I've seen before include "Blonde; impartial" , "'Just, meet (4)'" , "Just; gala" , "Having light-coloured hair and skin" , "honest" .)
