Can we ever imagine a world of black and white without any colours? Won’t it be a dull life without any bright charm? Think of the old movies in black and white and compare it with the glitzy and multi-coloured hued slick cinemas of today. Colours surely are an essential element of our lives. They are all around us. They add brightness and freshness to the world. Various aspects of our lives like our homes, work places, vehicles, food, clothes, stationary, toys, etc. have colours as the vital component. It is therefore important that the colours used in various applications follow the basic 3S principle; Shade, Stability and Safety. These are followed in various types of colouring variants such as acid dyes, basic dyes, paints, herbal extracts, etc.
