About the colours

This image is a composite of many separate exposures made by the ACS/WFC instrument on the Hubble Space Telescope using two different filters that isolate broad wavelengths. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F555W (V) Green: F555W (V) + F814W (I) Red: F814W (I)
