Color:

This image is a composite of separate exposures acquired by Hubble's WFC3 instrument and the VLA. Several filters were used to sample various wavelengths/frequencies. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:

F814W (I)	orange
F606W (V)	blue
VLA C Band Low (4-6 GHz)	red
VLA C Band High (6-8 GHz)	green
VLA X Band Low (8-9 GHz)	blue
