A shade jealous after love elopes initially (4,5)
I believe the answer is:
nile green
'a shade' is the definition.
(I've seen this before)
'jealous after love elopes initially' is the wordplay.
'jealous' becomes 'green'.
'after' says to put letters next to each other.
'love' becomes 'nil' (love and nil mean zero in cricket and football).
'initially' suggests taking the first letters.
The initial letter of 'elopes' is 'e'.
'nil'+'e'='nile'
'green' after 'nile' is 'NILE GREEN'.
(Other definitions for nile green that I've seen before include "Pale shade" , "Pale colour" .)
