To elaborate,
A black hole is formed when the mass of a dead star exceeds the Oppenheimer Limit.
There are two limits to a collapsing star's mass. The Chandrasekhar Limit is the point at which the collapse of a star is halted by the electromagnetic repulsion of the atoms from each other. White dwarfs are formed when the star's collapse stops at this point. Once past the Chandrasekhar Limit, the star's gravity crushes the electrons into the nucleus of the atoms thereby neutralizing the electrical charge of the nucleus. The protons and electrons "combine' and what you are left with is a huge mass of neutrons. This is the neutron star, and since elements are determined by the number of protons in an atom's nucleus, the star is not carbon. The star's collapse at this point is halted by the Strong Nuclear Force within the neutrons themselves. But if the gravity is strong enough, it will overcome the Strong Nuclear Force as well. This is the Oppenheimer Limit. Once past this limit, there is no natural force in the universe left to prevent gravity from crushing the star out of existence.
Does it have color? Possibly. Color requires the radiation of visible light. But since no light can escape the gravity field of the black hole, we will never know.

No. A black hole is a massive object that is compressed into such a small space, that you can actually get close enough to it (without being iside the object) such that you'd have to be going faster than the speed of light not to be caught in it's orbit. For this reason, light cannot escape a black hole's pull, which is why it is called a "black hole". No light can emerge from it so it appears as a dark spot in space.
