Color:

The image is a composite of separate exposures made by the WFPC2 instrument on the Hubble Space Telescope. Three filters were used to sample broad wavelength ranges and one filter was used to sample narrowband emission. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:

F814W (I)

red

F606W (V)

green

F450W (B)

blue
