Answer 1

Answer:

Neel is a chemical called Ultramarine Blue. It is a blue pigment consisting primarily of a double silicate of aluminium and sodium with some sulfides or sulfates. It is the most complex pigment found in nature. It is found in the natural state in the mineral of Lapis Lazuli. Now it is also produced artificially.

The name Ultramarine essentially means "Beyond the Sea", because it was imported from Asia by sea
