Saving color palettes to the system, windows version

[KJVG]

I am wanting to save my color palettes as system palettes and in the windows version I do not have that option. I'm also finding it virtually impossible to export the color palettes that I have created for the customer to have that is a separate file that can be opened by any other software.  I'm very new to Affinity and designing, your help is greatly appreciated.

System palettes are a feature supplied by the Mac OS, not by any Affinity or any other third party app. Any Mac app that supports that feature can create or use system palettes, for example the Mac OS Color Picker.

There is no equivalent system level feature in Windows that I know of.
