How about to make a few additional ship liveries , wearing them having some RP consequencies.

-pirate livery:
Some skulls would be nice
Wearing it makes all convoy treat you as hostile in unmonitored space
-serco military livery
wearing it makes all itani npcs treat you as hostile in unmonitored space

feel free to add more ideas

I'd like a flat black. The whole ship except the details perhaps.

The only ship that comes out black for me is the Vulture. The rest are usually just grey with some black sections (maybe).

How about instead of coming up with new liveries, which is immensely time-consuming for devs who have no time, just make the rest of the ship a color choice from a palette as well? I'm guessing it would be much simpler to implement and would afford many creative options-- monochrome, two-tone, accent, contrast, etc.
