Colourful line in undergarments (6)
I believe the answer is:
paints
'undergarments' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'colourful line in' is the wordplay.
I cannot really understand how this works, but
'in' is found in the answer.
The remaining letters 'pats' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for paints that I've seen before include "Makes picture with canvas and oils" , "Liquid pigments" , "Decorative coatings" , "Applies colour" .)
