Broke unit revealing shade on the outside (4,4)

I believe the answer is:

skin tone

'shade on the outside' is the definition.
(shade of one's skin)

'broke unit' is the wordplay.
'broke' becomes 'skint' (both can mean struggling financially).
'unit' becomes 'one' (synonyms).
'skint'+'one'='SKIN TONE'

'revealing' is the link.

I've seen this clue in The Guardian.
