About the colours
The HST image is a composite of separate exposures made by the ACS instrument on the Hubble Space Telescope. Two filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F435W (B) Green: F435W (B) + F814W (I) Red: F814W (I)
About the data

The Hubble image of Arp's Loop was created from HST Proposal: 10915 J. Dalcanton (University of Washington).
