Salmon perhaps that's potted for six (4)
I believe the answer is:
pink
'salmon' is the definition.
(thesaurus)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for pink that I've seen before include "... similar flower - colour" , "Flower - make knocking noise (of engine) - cut with zigzag edge" , "Put serrated edge on" , "Cut wavy edge on, plant" , "(Leftish) colour" .)
