The things are never the same in the way they appears to us. It is a great paradox in the universe. When we say the thing is orange in colour, in fact it is absorbing all the colour waves other than orange and is emitting orange colour waves. So it never appears to us what it is in reality. The plants looks green coloured but for the photosynthesis they absorb blue-violet and red colour. The so called black hole appears black because it is absorbing most of the light waves coming near it and in reality the light is captured inside it. So for us the things appears in the way our brain notices it according to it's capacity.
