What do I need to do to capture the same purple in the photograph from a purple object?

In most of the settings I use, the purple comes out as blue in varying tones and sometimes with a tinge of purple, maybe pale purple as well. What can I do to overcome this problem and the camera settings I use?
I use a Nikon D500 camera.

Set a custom white balance. Use a fully calibrated system. And be aware that most people's monitors are not calibrated, so they may see some color completely different than you see on your calibrated system.
