The colour red
“The color of your body — and love
Red is our color. Our bodies produce 2 million red blood cells every single second. Many creation myths claim that the first humans were made from red earth. The name Adam is derived from the Hebrew word for red. Humans are some of the only mammals who can see red.
We need the color red because it has a powerful effect on our brains. Scientific studies have found that the color makes us stronger, more alert, more competitive.
Many of us get red in the face from increased blood flow when we are angry, flushing from embarrassment or blushing after being given a compliment.
Red can also make us appear more attractive to one another, which is why red lipstick is on billions of lips.”
