Petals represented in crayon (6)
I believe the answer is:
pastel
'crayon' is the definition.
(I've seen this before)
'petals represented' is the wordplay.
'represented' indicates anagramming the letters.
'petals' is an anagram of 'PASTEL'.
'in' acts as a link.
(Other definitions for pastel that I've seen before include "Soft shade; crayon" , "Crayon - pale colour" , "Delicate colour found in plates" , "art work" , "Crayon - gentle shade of colour" .)
