All vessels containing blood would have red blood; in arteries and in veins and smaller vessels.
The blue appearance of veins is an optical illusion that comes from the way light works on skin. The veins look blue because they are closer to the surface, if arteries were not as deep, they would look blue, too. It has nothing to do with oxygenation of blood in arteries and all to do with the properties of light and skin.
Dilation of a blood vessel is the term for physiologic widening of the vessel. Abnormal widening of the blood vessel through a weakening of the wall is known as aneurysm.Dilation of a blood vessel means widening of the vessel.

Aorta
Yes. It depends on the blood vessel and where it is, but yes a rupture to a blood vessel can kill you. A blood vessel is more likely to "pop" or rupture if it has an aneurysm, which is a local weakness where the blood vessel has stretched from the pressure of the blood. This is more likely to result in death if it is in a large blood vessel or in a critical location, such as the aorta or a vessel in the brain.

Blood flow in the center of a large vessel is faster because the walls of the blood vessel may have a buildup of cholesterol on them.
