The immune system is a miracle of creation. It is the most efficient mechanism that protects us from harm. It is so complex that the scientists still do not fully understand it. What we call the immune system is a tireless network of organs, proteins, white blood cells and other cells and tissues. Our innate immune system is there for us from the moment we are born. The adaptive immune system is ever-developing when our bodies are exposed to viruses, bacteria, toxins etc. 

Indigo has been with us for thousands of years but it was Sir Isaac Newton in the 17th century who used the term ‘indigo’ to describe a colour when he demonstrated that the white light was composed of 7 visible colours, indigo being one of them. Until then, the word ‘indigo’ was used for the dye, desired by many. The dye was made from a plant called Indigofera Tinctoria, which had been cultivated predominantly in Asia and parts of Africa; some sources mention Peru as well.

Blue is the favourite colour of all friends I had this info available for!

Red is one of the most represented colours in nature. It is a primary colour and in the history of humankind, it is one of the first colours that were used in art.

“Richard of York Gave Battle In Vain”, I was in awe when I was learning English and came across this wonderful mnemotechnic verse to remember the colours of the rainbow. We did not have anything like that! I never thought it was important either, although, as is the case with most people, I love rainbows. Aren’t they magical? They make us feel good. But what are they other than optical illusions?
