It will surprise you to know that tattoos, as a body art, date back to centuries.

Nobody knows the exact discovery date of the colourful tattoo ink. The caveman used the soot from his fires to form the first black tattoo pigment. Historical sources confirm red, green, brown and yellow as successive additions to the palette.

Red, orange and yellow were formed from cadmium; yellow and white from zinc; green and violet from aluminium; blue and green from copper; brown and black from iron.

Currently, colourful tattoo ink types include those which glow in the dark and react to non-visible UV light to produce colourful glows. You should really check them out.
