We construct invariants of -colored spherical graphs from traces on ideals in a pivotal category . Then we provide a systematic approach to defining such traces from ambidextrous and spherical traces on a class of objects of . This extends the notion of an ambidextrous object of a braided category given by the first two authors in a previous work.
