Black absorbs all the light, so how do we see black things?

We see things in different colours because light (usually white) reflects off surfaces and reach our eyes with a different frequency, for some is absorbed. When NO light reach our eyes, it simply appears as black. You can see this as some form of 'natural default' (i coined this term myself).
To help your understanding, think of seeing a piece of paper filled with different patches of colours and holes, placed in front of vaccuum space. The black that you see will be the holes where no light get bounced off.
Hope this helps=)

When there is no light you have black. This happens because all the light is cutoff (no light @ night you turn off the light) or the object absorbers all the light.
Such bodies are call black bodies.
There are three main colours Red, Yellow and Blue. All other course can be obtain from mixing the combination of these two or three in certain ratios.
Try mixing them one third each.

There seems to be a lot of confusion on the meaning of the word "colour". A definition obtained by Google search is:
color: a visual attribute of things that results from the light they emit or transmit or reflect;
This is the best meaning to use in our context. It should not be confused with the light itself!
An object is green, if the light coming from its surface looks green. An object is black, if no light comes from its surface.
It is clear that both green and black are attributes that describe the object's appearance. The reason for its appearance is in the way it emits/reflects/transmits light. So, black is a colour.

Yes ,black is a real colour ,as this is the colour which absorbs the light , it is seen in context of other surrounding which are coloured and if surroundings are black then we will not able to see anything.

Black is not a colour, it is not seeing any colour. In a surface where light of any colour is absorbed, it is black.

No, black is technically not a color. When we see color, we see the frequency of light bouncing off of the object (IE a small part of the visible light spectrum). When something appears white it means that all of the visible light waves being emitted from the object. Black is the opposite. Meaning, instead of emitting light, black objects absorb light waves.

You can use it as an actual colour in pens etc, but actually it's just the absence of light. If you look real close, you see there is no pure black, it's just all shades of black. But real black we can't see.

Black n white are both neutral colours, when a surface reflects all the colours tnen we see white,if a surface absorbs all the colours then it is black.
if we mix all the colours together the end result is black.

Black is not a tint, shade, or colour. Black is an absence of light. Wherever light is not, there is black.
