Colour part of Vespa in Tuscany (5)
I believe the answer is:
paint
'colour' is the definition.
(I know that paint is a type of colour)
'part of vespa in tuscany' is the wordplay.
'part of' says the answer is hidden in the clue.
'PAINT' is hidden within 'vespa in tuscany'.
(Other definitions for paint that I've seen before include "Artistic medium" , "A pint of liquid decoration" , "Coloured liquid in tins" , "Artist's material" , "Catch a likeness" .)
