Calc: Use self-defined colors in style / add them to palette [closed]
I'm using LibreOffice 5.3.5.2 as provided by the reporitories of my OpenSuse 42.3 installation.
If I want to change the background color of a cell in CALC by hand, there is an option to choose any possible color below the predefined palette.
Now, I would like to define a style, but there, only the predefined palette is available.
My first thought was that this is just inconvenient, since one can add colors to the palette somewhere in _tools > options_.
__But I'm, quite surprised that there is no entry to alter the color palette__
__Furthermore, this only applies to background color, text and border color can be defined freely!__
So, how do I use self-defined colors in CALC styles? Since I'd like to set up my own color scheme, how do I add colors to the palette?
