So, the navy selected two new Admirals. These Admirals were given the secondary colors, which are a mix of the primary colors. The secondary colors are Purple, Green and Orange.
These new Admirals like the previous ones have colors and animals in their aliases. Wisteria (which is the shade of purple) Tiger translates to(Fujitora) and Green Bull translates to “Ryokugyu”, these Admirals have a different type of Devil Fruit.
We have already seen the latter two, which leaves the just the Orange Admiral out. It is also important to note that orange is a mix of Yellow (Kizaru) and Red (Akainu).
