Actually it is only possible to choose between 1 of 9 colors. Is there a way to add additional colors to the outlook calendar? Or is there a hack to change the existing ones?

If you mean the color of the whole calendar, I'm afraid that Outlook could only support the 9 colors for now and we could not make changes to it. If you still want more colors to be available, please try voting in the Outlook User voice, Microsoft may notice it and add it in the later version.
Looks to be a fixed palette, which can't be edited from File > Options > Calendar either.
Older versions of Outlook allowed custom colours (I think 2010 or 2012), but just as desktop customisations were dumbed down for Windows 10, the same applies for more recent versions of Outlook. Perhaps this explains how Lisa's colleague above managed to use a non-standard colour.
