Right, so I will summarize the issues with the suggestion.
Ship sprites are basically a collection of 2D images if you notice a full circle of a ship it is a profile of a dozen
odd angles depending on where you are pointing. There is also a separate sprite for superstructure and other
misc. Now counting the number of ships in game some dev will have to color each of these angles. Now there
is an entirely another set for ships sinking. And I assume you want more then 1 camo scheme for your akagi,
if you're feeling pink one day or woodland another.
The other thing with custom sprites is the impending lag it will cause. and maybe I don't want to suffer lag at
the cost of your pokadot bissy. The very solution is that you can edit sprites on your side but no one else can
see it. This very solution exists if you would just search.
As for weird shell stuff, you can go back and install the christmas graphics. If you want to be cool, win an EBB
or a rental BB3 which are basically camoed ships.
