morphology–color–density

Worked on figures for the future paper on the morphology–color–density relation. We have been saying for years (eg, here and here) that indirect indicators of galaxy morphology do not correlate directly with environmental density, but that they correlate with galaxy star-formation history, which themselves correlate with density. I realized (very late, I must admit), that we can show this directly by simply showing true-color images of the damned galaxies; everyone can "do" morphology however they want on those images.
