Why are Subs red on the bottom?

Copper oxide has a reddish tinge, thus giving the paint it's much famous red colour. That is why ships are painted red below the hull. Tri-Butyl Tin(TBT) had been mainly used as a primary toxin against the growth of marine organisms on the ship's hull even a few years back.

Why are cruise ships white?

The scientific reason:

White is the best reflector and the worst absorber of sunlight. For this property of the colour, white exteriors save the ship from getting heated up, reducing the burden on air conditioning systems.

Why are military vessels GREY?

Haze gray is a paint color scheme used by USN warships to make the ships harder to see clearly. The gray color reduces the contrast of the ships with the horizon, and reduces the vertical patterns in the ship's appearance.

Why are submarines called U boats?

Why are ship hulls black?

It is easy to imagine how the clouds of coal-dust during loading would ruin the appearance of even the most beautiful hull, so, to keep the vessels looking neat and to save time cleaning the hulls in port every time, companies usually opted for dark colors.
