Stuck on 4
4A 8's maybe a good home (7) ----a e (8A is 'squeeze')
4D Contemporary recess (6) --E-A-
5D Red fish (4) --O- (I thought that was a fisherman's euphemism for 'salmon'?)
21A Pinky language (5) N-R-L
Thank you, Writes Bad. If 'red fish' is 'RUDD', though, 'Work out colour', which I have answered 'OCHRE' (anagram of 'chore'), becomes 'D-H-R'. How does that work out?
