Ways to have a dark(er) background set up

GanttProject Desktop Support
1

Hi people,
I have just discovered G.P. an hour ago. I’m used to paper Gantt, so a virtual version of this is great to me. Now…I’m under Linux Zorin 15.

Question :
Is there a way to customize the Background along with text colors ?

The idea being, have all backgrounds, Gannt (main window) and task list (left window) displayed in Dark (Black or darker greys) and text in lighter colors (white, etc…)

*Extra request : customizing the general App frame.

any tweak possible from a config file, I do not mind digging into some script, depending the coding language ?

Thanks a lot,
Keep coding !

I don’t think that it is doable in reasonable time, sorry. There are just too many technologies involved.
