An Indian industrial designer was asked to suggest a new colour shade for the newly launched Maruti Zen. The colours popular for the similar cars by Maruti, the 800, were Maroon Red, Dark Blue Grey, and Dark Green Grey. Now the company wanted a new shade that would cater to the female market.

Study of the psychological setup of the mind of the typical Indian woman played a key role in this problem. The new colour chosen by the designer was lemon yellow, which the company officers were reluctant to introduce. The designer somehow convinced them, and in reality, the colour shade proved to be very popular, especially amongst women.

Color and light play a key role, though generally unrecognized, in our lives. The above example shows the same. It is an example that shows the same. It is an example of the proper use of colour for the product. But many a time, the colours are used without giving proper thought to the psychological and psychological effects of the colours. This leads to bad colour design, which can cause anxiety, stress, and visual disorder and be the host to many other problems.

There have been numerous attempts by people all over the globe to understand the role of colour in human life. Many experiments have been done in history to detect the influence of colours on the human mind, both scientific and mystic. The main hindrance towards creating a set of identified rules or an elaborate theory on the behaviour of the human mind with respect to colours is that the results of all such experiments are subjective. Now, the days have changed and science has emerged with new tools for research. Today, thanks to sophisticated techniques of research and analysis, we know that colour affects cortical activation (brain waves), functions of the autonomic nervous system (which regulates the body’s internal environment), and harmonal activity, and that colour arouses definite emotional and aesthetic associations. In short, our response to colour is total; it influences us both psychologically and psychologically.
