Left again the day after (3)

I believe the answer is:

red

'left' is the definition.
(I've seen this in other clues)

'again the day after' is the wordplay.
'again' becomes 're'.
'the day' becomes 'd'.
'after' is a charade indicator (letters next to each other).
're'+'d'='RED'

(Other definitions for red that I've seen before include "Very angry, seeing this" , "Bloodshot" , "14 -- breed of 4" , "Colour of Merlot wine" , "Merchant flag" .)

I've seen this clue in the Evening Standard.
