Since were not talking about blackness, just black (like the color) i think
eventually we could make something that emits black but not yet.
White reflects light, including all colors, while black absorbs light, including all colors. This means that white does not reflect black, but rather all colors, and black absorbs light, even white light.
Yes, black light is a type of ultraviolet light that emits mostly ultraviolet radiation and very little visible light. It can make certain objects glow in the dark.
In a black hole, gravity is so strong that nothing, not even light, can escape. This means that whatever goes into a black hole is trapped inside forever, making the saying "what happens in a black hole stays in a black hole" true.
Blue objects absorb most of the red light that hits them, reflecting very little red light back to our eyes. This causes the object to appear black in red light because red light is the only color that can reveal the object's true color.
A true black will not reflect any light of any colour.
really dark gray or light black
When using pigments, as in paint, black is all the colors mixed together, and white is a lack of color. So in that sense, black can be a "true" color. If you are studying the colors in light, black is simply the absence of light, while white is the combination of all colors.
No, there is no such thing as natural black hair, it is just really dark brown or marron colored hair. It is possible to dye your hair black though.
Yes, light is the only thing that can escape a black hole's gravitational pull. Nothing with mass, including matter and other forms of energy, can escape a black hole once it crosses its event horizon.
White reflects light, including all colors, while black absorbs light, including all colors. This means that white does not reflect black, but rather all colors, and black absorbs light, even white light.
A object appears black when it reflects or emits no visible light. True black is very uncommon because almost no substance can completely absorb light. http://en.wikipedia.org/wiki/Black

Any object that is black will theoretically not reflect any light.
a rock
Light cannot escape from a black hole due to its extremely strong gravitational pull. The gravity of a black hole is so intense that not even light, the fastest thing in the universe, can escape its grasp.
Black Hole - A thing found in the Universe which is color :-) - Thing that can escape Black Hole are examples: Volume Light Universe - Found outside our planet called "Earth" - Thing which don't occupy - Big empty space
The black thing in the center of the eye is called the pupil. It is an opening that allows light to enter the eye and reach the retina, which is responsible for processing visual information. The pupil adjusts in size to regulate the amount of light entering the eye.
