An object that reflects all light waves that strike it appears the same color as
whatever light illuminates it. Consider a piece of tissue, or a mirror.
Black is the color that absorbs the most light energy because it absorbs all wavelengths of light, converting them into heat energy. This is why black objects feel warmer when exposed to sunlight compared to objects of other colors that reflect light.
For exactly the reason that you call it a "a green object". You describe it that way because most of the time, when it's being illuminated by light of all colors, the only color that it does NOT absorb, and that remains to bounce off of the object and be seen by your eye, is the green. When there is no green light striking the object, it can't reflect any light to your eye, and it appears black.
Objects are coloured because they absorb certain frequencies and absorb others. For example a green object has absorbed red light and what was left, the green light, and so on. A white object reflects all the frequencies (colors), a black one absorbs all.
"Black" means "no light". If something looks black to you, then it absorbs everything and reflects nothing.
Light is really all the colors of the rainbow for example if and object is blue it absorbs all colors except blue so a white object would look white because it REFLECTS all the colors of the rainbow a black object looks black because it ABSORBS all the colors

A blue hat looks black in a dark room because the lack of light prevents our eyes from perceiving its color. Colors are determined by the wavelengths of light that objects reflect; without sufficient light, the hat does not reflect enough blue wavelengths for our eyes to detect. Instead, it appears as a shade of black or gray, as the limited light makes it difficult to distinguish its true color.

Let's clarify that the "blackness" of a black hole is of an entirely different type than that of black surfaces in general. A black surface will absorb light, but it will also emit light according to its temperature. A black hole will absorb light, but will not emit anything, since gravity basically lets nothing escape (except for an insignificant amount of Hawking radiation). In general, white objects reflect more light than black objects. Please note that the Moon looks fairly bright if you look at it at night; but actually, its albedo - the amount of light it reflects - is only somewhere around 5%.
We see things as black when there is no light coming from that direction. Space is mostly empty, and neither generates light or reflects it, so it looks black. We only SEE things that reflect light, or that generate their own light.

"Black" means "no light". That's why a dark room looks black at niight.If an object really looks black, then you know that it must have absorbed any lightthat hit it, because there's none left to bounce from the object into your eyes.
No, objects absorb some colors of light and reflect others. The color that an object appears to be is the color of light that it reflects. For example, a red apple looks red because it absorbs all colors of light except for red, which it reflects.
A green object would look blaack in a red light because coloured objects absorb all colours except the colour they are, so a green object absorbs 6 colours (red, orange, yellow, blue, indigo, violet) and reflects 1 (green). In this situation, there is no green light to reflect and it can't reflect other colours, so it looks black. :)
Space looks black because for the most part it is empty - a vacuum. Space is in fact full of 'light' but without anything for that light to reflect/shine on to, it will appear black. Look at the Moon and you will only see the portion of it's surface bathed in light from the Sun, the rest will appear black (although even the dark side of the moon is actually faintly illuminated from distant stars).
