This image is a composite of separate exposures acquired by the ACS/WFC and WFC3/UVIS instruments. 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:

F275W (UV) pink
F336W (U) purple
F438W (B) blue
F555W (V) green
F814W (I) red
F658N (H-alpha+[N II]) red
