  We introduce a general definition for colored cyclic operads over a symmetric
monoidal ground category, which has several appealing features. The forgetful
functor from colored cyclic operads to colored operads has both adjoints, each
of which is relatively simple. Explicit formulae for these adjoints allow us to
lift the Cisinski--Moerdijk model structure on the category of colored operads
enriched in simplicial sets to the category of colored cyclic operads enriched
in simplicial sets.
