% 90 of carbon black(black color) is consumed in tyres industries . Adding carbon black increases long life of tyres (9 – 10) times comparing with tyres which are not containing this substance .
David Oulton
Within any given material the colour is caused by photon stimulated electron resonance and hence light absorption. In each instance a light absorbance band of characteristic width and spectral location is evident. Thus when blue light is absorbed we are left with reflected light of a yellow or orange colour. In the case of black materials such as carbon black the resonance mode is complex and multi-frequency and the light absorbance bands absorb light at all visible wavelengths.
