In libreOffice 6.0.7.3 on ubuntu can a new colors be added to the any of the included color palates?
These are the colors in writer that are associated with the font colors, background colors, and highlight colors. All the instructions i can find on the web points to "Format - Area and click the Colors tab, but this version does not have Area in the Format drop down menu. In all prior versions of LibreOffice this was accessed through Tools > Options…LibreOffice Writer > Colors but that selection “Colors” that is not there either on this version: 6.0.7.3.

Also: Is there any way to save and upload these user defined color palates once they have been made?

Have a look at this theme.
