| Color: |
These images are 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:
| F435W (B) |
blue |
| F435W (B) + F814W (I) |
green |
| F814W (I) |
red |
|
| F555W (V) |
cyan |
| F814W (I) |
orange |
