They are the pan slavic colours? What about France, UK, USA, Netherlands?
coincidental with france uk and usa - russian flag was based on dutch flag - russian flag then inspired pan-slavic flag
the colors come from the pan slavic flag which is blue-white-red (yugoslavia would later choose to use this flag) was first chosen during the 1848 pan-slavic congress in Prague and was based on the russian flag (white, blue, red) because they were the only free slavic country - russians got their flag from peter the great admiring Holland (peter the great loved ships and the dutch were a great maritime power) and so he based his naval/merchant ensign on the dutch flag and with all those russian ships flying it it eventually ended up as the russian national flag
in 19th century the russian royalty had the white-gold-black flag but it was only flown over imperial residences i believe and was rarely if ever seen outside that context, the white-blue-red was popular amongst everyday use and was widely used
pan slavic colors are still used today by the flags of croatia, slovenia, serbia, czech rep., slovakia, and of course the russian federation (and autonomous Crimea in ukraine and several republics within the russian federation), the colors were also used historically in some polish revolutionary flags during the various uprisings in the 19th century
so with all that said flag op posted should be the default one in game imo
It is the Russian flag if Reactionary Rebels win.
Don't ask how I know this.
i think it should be opposite, the black-gold-white for reactionaries and white-blue-red standard
