Is there a way to save a color palette file to export it to another computer?

I am using LibreOffice 5.4.2.2.
I created a custom color palette on my desktop and would lke to export it on my laptop.
I can’t find where this file is saved. I have looked for .soc files but did not find one.
i’d like to know if this file can be found and can it be saved, exported and then imported into an other computer.
Thank you

If you don’t want to fiddle with the values in your user profile’s registrymodifications.xcu file (which I presume) then use the Custom palette export extension. For details see also this LibreOffice Design Team blog post.
