Color of annotation

Hello,
I have a little issue with your library. I need to add some annotation to PDF document. It works fine. I have set some color for this annotation and it works great, but if I change the mode from day to night (Global.dark_mode), the color of my annotation has changed.
Is there any way how can I disable this? For example it means, that if I add red annotation, this annotation must be red in day mode, but it must be red also in dark mode. Note that I have a premium licence, so I can modify all classes.

Thanks in advance for your reply.

no ideas about this.
all objects in page are rendered in 1 bitmap, and it invert pixlels for whole bitmap object.

Ok, thank you for your response. I will try to change the color of annotation when I switch from day mode to dark mode.
