Star Destroyer White?

Okay, so it's time for me to pick a bone.

The Star Wars books deal a little bit with a former smuggler/information broker/gangster named Booster Terrik. Through a twist of fate, he ends up being the only civilian owner of an Imperial-class Star Destroyer (the Errant Venture).

Now, according to the book I, Jedi, Booster wants to paint his Star Destroyer bright red. Funny, sure, but he takes it as a personal slight from the Emperor. The only color paint in sufficient amounts (and inexpensive enough) to do the job is, of course, "Star Destroyer White." This make sense, Mon Calamari Star Cruisers (Admiral Ackbar's cloud-like ship in Return of the Jedi, if that helps), which are similar in size, are also the same shade of white.

My beef is as follows. Over the course of the Saga, the Empire builds six Super-class Star Destroyers: Executor (Vader's ship in Empire Strikes Back), Lusankya, Iron Fist, Razor's Kiss, Indimidator, and Knight Hammer. (Sadly, I did NOT look up that list.) These ships are 5 times the length of an Imperial-class Star Destroyer, and they're painted gray. With that in mind, why could Booster only get White?

Not that gray is much better, but still. With each SSD being 8km long (and proportionately wider and taller), they would require a MASSIVE amount of paint to touch up.
