  13. Color applied to IR mosaics The color images are a reconstruction or a visualization of the different energies that are inherent in the capture of the light in the images. The colors are not arbitrary. Hubble Science Briefing 4/25/13

  14. Color composite The initial color composite, “flat” in tone, includes some artifacts. Hubble Science Briefing 4/25/13

  15. Adjusted image Completed color composite Hubble Science Briefing 4/25/13
