Manifestation in pink (11)
I believe the answer is:
incarnation
'manifestation' is the definition.
(thesaurus)
'in pink' is the wordplay.
'pink' becomes 'carnation' (carnation is a kind of pink).
'in'+'carnation'='INCARNATION'
(Other definitions for incarnation that I've seen before include "Personification of an abstract idea" , "Existence" , "Epitome" , "Living embodiment of, eg, a deity" .)
