Red, as Wikipedia notes, is “the color at the end of the spectrum of visible light next to orange and opposite violet.”
It’s also both one of the “additive primary colors of visible light, along with green and blue”… AND “one of the subtractive primary colors, along with yellow and blue, of the.. traditional color wheel used by painters and artists.
“Since red is the color of blood, it has historically been associated with sacrifice, danger, and courage.
“Modern surveys in the United States and Europe show red is also the color most commonly associated with heat, activity, passion, sexuality, anger, love, and joy.
“In China and many other Asian countries, it is the color of happiness.”
Of course, most STOP lights and stop signs are red. This means that RED is a contradiction. Action and stopping. Anger and joy.
I thought I’d list some RED songs. The links to the titles are descriptions of the songs; the links to the artists are the recordings. The chart action refers to the Billboard (US) pop charts.
