Certain colors from older versions of LibreOffice are not on the current color palettes, and I have not been able to re-produce them using the custom color tool. Is there any way to make the colors from previous versions an option rather than only offering the palettes?
The colors of older documents should be included in the “Document Colors” palette. I hope it has already been implemented. You can try. For this you should still specify your LibreOffice version and the OS.
