About the colours

This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope. A single ramp filter was used to sample several wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: FR782N (750 nm ) Green: FR782N (770 nm) Red: FR782N (790 nm)
