These images are a composite of separate exposures made by the ACS instrument on the Hubble Space Telescope. Three filters were used to sample various broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

F435W (B) blue
F550M (V) green
F625W (r) red
Orientation: Hubble ACS image of NGC 1275
