Color–color diagrams with the various sequences highlighted in different colors. The full sample of matched sources is indicated with black dots. Orange, gray, red, light blue, and blue dots indicate the approximate loci of GCs, MW stars, passive galaxies, blue galaxies, and star-forming galaxies. The left and middle panels in the lowermost row show the same color–color diagram, although in the second row we do not use colors for the sequences identified. The total overlap of the identified sequences in the lower right panel is notable.
