Green note (7)
I believe the answer is:
natural
This might be a double definition.
'green' is the first definition.
Both the answer and definition are adjectives. Maybe you can see a link between them that I don't see?
'note' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for natural that I've seen before include "Simpleton" , "Normal - genuine" , "Unforced" , "Unrefined person" , "white key on a piano?" .)
