Why is half of the ship black and half of it is silver colored?

that's because the bottom as seen from orbital entry is, has a heat shield on it. So the black there is the heat shield and then the core structure of the rocket is a special alloy of stainless steel and that's where you see the sort of shiny silver parts are stainless steel.

The reason for steel over aluminum is that the heat of atmospheric entry and the heat of the rocket engines is enough to easily melt aluminum but steel is much more resilient against both a sand heating, but especially the re entry heating.

And you don't have to paint it, which is actually very difficult at to paint a large object that is going through cry genetic cycles and have the paint stay on.
It's quite challenging

BREAKING: 10-year note yield rises as high as 4.37%, the highest since 2007.

Rates continue to rise despite a Fed rate pause expected.
