Color

The image is a composite of separate exposures made by the ACS and WFPC2 instruments on the Hubble Space Telescope. Several filters were used to sample broad wavelengths. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

ACS F814W (I) red
ACS F555W (V) green
ACS F435W (B) blue
WFPC2 F814W (I) yellow/orange
WFPC2 F555W (V) cyan/blue
