I need fill and lines to always be RGB and would like RGB to be the default.
I seem to have successfully gotten the "Default RGB palette" to stick.
Regarding the "Object properties" docker: How do I set those line and fill colors' default at RGB?
How do I check to make sure that an object's or line's color is RGB?
for new files, go to Tools / color management / default settings and choose RGB as default color mode. For previous files, go to Tools / color management / document settiings and choose RGB. The color palette will change automatically to RGB after change the color mode of the document.
EDIT: sorry, I didn't notice it was about X4. You don't have both options (default and document settings) only one general setting for all files, also under Tools / color management.
Sorry X4 ignore me
