What is the Universal Colour of Money?

Some years back my elder brother engaged me in a lengthy conversation which centered around money and how it will continue to play a vital role in the world system through out time. As our communication progressed he told me of his quest to know the universal color of money and what it's truely represent, so he went further to get an answer to his question. Days after he had a dream and suddenly heard a voice talking to him about Money. In his unconscious realm the person said the Universal colour of money is Red because it's what everybody is using for the exchange of goods and services and also it plays a vital role like the blood flow so in our veins as humans. We both came to conclusion that money changes things completely and that a life without blood is equals to death so it is with anyone who doesn't have money. The Colour of the blood is red, and money is what sustains our physical social life that is why it is called liquid capital. So money should be valued just like how we value the blood in the body. I round up by saying our intangible ideas should should be used as an exchange for money.
