It helps make the village colourful (5)
I believe the answer is:
green
'it helps make the village colourful' is the definition.
The definition suggests a singular noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for green that I've seen before include "one may be putting on" , "Unripe; envious" , "Ecologically beneficial" , "Naive; colour" , "Environmentally concerned" .)
