The History of the Color Red

More than 40,000 years ago, hunters and gatherers used red clay to make paint. The Paleolithic people buried their dead with red powder for protection from evil spirits. Red is also common in ancient art, with cave paintings across continents created by red ochre. Ancient Romans favored cinnabar for decorations, and Renaissance painters used vermilion paint.

What Is the Meaning of the Color Red?

The color red is significant in many cultures. It is associated with love in Western culture, and it symbolizes good fortune and joy in Asian cultures. For this reason, it’s a prominent color in Asian weddings to bring love, fertility and good luck.

Many world leaders have worn red to symbolize their power. Princess Elizabeth I wore a red dress and coif in her portrait to symbolize political and moral strength. In Chinese philosophy, red is associated with fire and connected to aggression, confidence and leadership.

The Psychology of the Color Red

Red provokes strong, often opposing emotions, such as love and anger. It conveys literal danger, such as stop signs and traffic lights, and metaphorical danger, such as “red flags” or being “in the red.” Exposure to the color red can cause increased blood pressure, respiration rate, heart rate and metabolism.

How Is Red Dye Made?

Red pigment comes from the deep red ink gathered from cochineal insects. Farmers in Central and South America harvest these bugs from the prickly pear cactus and smash them into a grainy red substance. This substance is processed into a powder or liquid. The Aztecs invented this techniquein the 15th century. This practice is one of many organic and synthetic methods of making red pigment.

Since the bugs are so small, nearly 70,000 of them are required to produce one pound of dye.This dye appears as carmine, natural Red 4 or cochineal extract in ingredient lists on food labels. It’s also common in cosmetics.

Measuring the Color Red

At one of the longest wavelengths, red is easy for humans to identify. A colorspectrophotometer measures the color red by using sensors to separate transmitted or reflected light beams into their component wavelengths. These numerical values for the red shade determine if the production processes create consistent results.
