Martian Aurora: to see or not to see?

I gather that Mars regularly experiences aurorae, this despite the planet's lack of a global magnetic field. It's also stated that these aurorae occur in the ultraviolet wavebands. I assume from this that these displays are invisible to the human eye. This being so, I'm intrigued to come across artistic interpretations on the net that suggest how "auroras will look on certain parts of Mars" (to quote the text accompanying one such image). Does this mean that aurorae are actually visible, after all? Or am I missing something here?

Mars has a weak magnetic field because it's core has cooled and solidified this has allowed the solar wind to scour away most of its atmosphere. That said NASA has observed aurorae on Mars, there is plenty of information on line.
