Color: This image is a composite of separate exposures acquired by the WFC3 instrument on the Hubble Space Telescope (HST). Several filters were used to sample broad and narrow wavelength ranges. 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 as follows:
NGC 4150 Wide-field
F814W (I) red
F555W (V) green
F438W (B) blue

NGC 4150 Inset/Nucleus
F657N (H-alpha) red
F438W (B) green
F225W (UV) blue
