Thank you! It's a mix, if you click into the images you can see details, especially on the latest ones. Ones labeled broadband or have LRGB capture details are true color, the ones labeled SHO or narrowband are in the hubble palette which assigns Red Green and Blue to Sulfur II, Hydrogen Alpha and Oxygen III.
Is that really the color they look like to the naked eye (i.e. in the visible spectrum) or did you have to postprocess them?
