Color-period diagrams for six age groups shown in order of age (left to right, top to bottom). The gray dots are open cluster stars, and cluster stars of the same age group are highlighted. Components of wide binaries are connected by lines and overplotted. Red circles indicate those agreeing with the slow rotator sequences (S), green squares are those connecting to a fast rotator (F), and blue boxes are those altogether disagreeing with the cluster behavior (C). Open symbols denote doubles (i.e., wide binary components identified as binaries themselves). Numbers in the upper-left corner of each panel enumerate the binaries in that age group, distinguished by class (see color coding). Numbers in parentheses indicate how many of these are hierarchical (i.e., where a component itself is a binary). The Sun is shown with its usual symbol. As in Fig. 2, vertical gray lines indicate the Kraft break and the fully convective boundary.
