Hey there ! Just adding my thoughts on this: It is very much possible to roleplay as a blue, just stick to your role and give people a chance to get to know you as a roleplayer

Don't feel turned down if on your first night of roleplay you didnt get the expected reaction from people you'd like to see. I roleplayed blue for a very long time and yes it was harder then now when i am Orange, but once people know you it gets easier and then you do not need a guild or need to be orange
Happy roleplaying !
