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