Color: This image is a composite of separate exposures acquired by the WFC3/UVIS instrument. Several filters were used to sample various wavelengths. 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:
F606W (V) (of comet) grayscale
F606W (V) cyan/blue
F814W (I) red/orange
Orientation/Scale: Compass and Scale Image for Comet ISON
