Carbon and graphite is highly extended fused benzene rings terminated with quinone groups and phenol groups. This allows the pi electrons to delocalize over large areas. This delocalization collapses the molecular orbitals to a point that they absorb all light in the visible region. Hence it appears black.

Why black shale weatheing is important?
Black shale contains a lot of carbon - this is what gives it its black colour. So, when it weathers, it releases carbon as carbon dioxide (a greenhouse gas), which may have an impact on global warming.
How do you know that the ash is free from carbon?
we can assess the presence or absence of carbon in ash from the colour of the ash:- If ash is greyish to blackish in colour then carbon is present in the ash. If ash is bluish grey to brown in colour then the ash is free of carbon.

Why are tires always black?
During the process of vulcanisation of rubber to make it sheer resistant to make tyres out of it, a certain proportion of carbon is mixed into it. Without this procedure the tyres will not be able to withstand the friction n stress of the road. This carbon is responsible for giving tyres the characteristic black colour.. When ozone combines with ultraviolet light from the sun, it attacks the tire polymer. To prevent tires from rapidly deteriorating, a sacrificial absorber is used, "carbon black" - which, fittingly, makes tires black
Why are black diamonds black?
