Greenish-yellow (10)
I believe the answer is:
chartreuse
I believe this is a double definition.
'greenish' is the first definition.
(thesaurus)
'yellow' is the second definition.
(thesaurus)
(Other definitions for chartreuse that I've seen before include "green liquid" , "Carthusian liqueur" , "Green or yellow liqueur made by monks" , "drink" , "Pale green-yellow colour" .)
