OK. Bleached to just the right degree (4,6)
I believe the answer is:
fair enough
'ok' is the definition.
(something fair enough is acceptable)
'bleached to just the right degree' is the wordplay.
I cannot quite understand how this works, but
'just' could be 'fair' (just can mean fair in the sense of showing justice) and 'fair' is located in the answer.
The remaining letters 'enough' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for fair enough that I've seen before include "Very well" , "understandable" , "OK?" .)
