Black holes, as the name would infer, are black due to the fact that nothing, not even light, can escape their gravitational pull. The only reason that we actually know that black holes exist is not because we see them, but because we see the absence of the stars around them, and we see gamma rays emitted from condensing stars.

If a black hole could exist it would be a 2 to 3 solar mass sphere 3 km in diameter whose surface gravity would be such that the escape velocity would be greater than the speed of light.
Since no electo-magnetic radiation could escape it would be invisible.
It would act like any other celestial body so would be detectable through it's influence on other celestial bodies.

This could sound weird, but black holes if they looked like anything would probably look ultra-violet because the intense energy produced is almost entirely on one end. But the gravity is so strong that nothing escapes, not even UV waves. Everything is absorbed in, except for jets of infrared light at either pole. I have my own conclusions for this.

As we know that with the help of light only we can see any object around us and their colors.( because when a light falls on an object then it absorbs all the light exept the colour of light to which we imagine the colour of that object. Due to which it reflects that color of the light to th other places and to our eyes also. For, example the colour of the leaves is green because they reflects the green colour and absorbs all other colour of light that falls on them.). So, Similarly we know that the black hole do not allows the light also to go. It absorbs all the light. So, it is having a black colour.

Black Holes are regions in space with such a Large Gravity that nothing : Not even Light escapes from there.
These are not "Visible" as such to Telescopes etc; but only their presence can be detected .

Black - light can't escape as it is not fast enough. Nothing escapes black holes - the only reason we know they are there is gamma ray (?) being given off by stars getting condensed.

Black holes are green.

It's black. Because it does not reflect light.
But you can see different colours of its jets. Jets are two opposite ends of black holes from where energy come out.

black holes basically dont have any colour...they can be seen because of the stars around it... so they dont hav any colour..they just absorve the light that comes around it..

Now that you have your legitimate answer, lets talk about the other type...lol.
