Osiris: [Suggestion] Menu color changer

[Flaam]

Can you add a button in the visuals/misc menu to change the menu/gui color (color scale+rainbow)

I can implement menu style editor if more people would be interested.

Menu style editor sounds good.

I have implemented menu coolor editor in my build of Osiris but it's 3 different sliders instead of a single color edit box. I could share that but I'd rather prefer a single color edit box

Added.
