  1. The first two columns for each collection, “lists” and “ints”, report the percentage of lists (i.e., colors) and integers (stored reference identifiers) that belong to all colors within a given density. The last row, “Total bpi”, is comprehensive of the space spent for the integer lists themselves and the space spent for the offsets delimiting the lists’ boundaries
