With the Chimaera in Rebels we've seen that despite the Imperial Standard paint scheme reinforcing uniformity, there are exceptions where designs can be painted onto a flagship. Thrawn may be the only exception to the rule. However I like to think that just as other aspiring and envious Imperial Officers copied the uniform of Tarkin (in the novel Tarkin, Tarkin designed his own uniform that became the Imperial Officer Uniform we all know and love) in an attempt to glean some of his greatness others would likewise copy Thrawn.
I was thinking that while in Armada we rarely ever see the ventral part of an Imperial vessel, it would be cool to see if people paint their own designs on the ventral hull. Thrawn has a Chimaera on his ship what does you Fleet Admiral have if anything?
