The Red Pigment

The distinct red color is produced by a pigment called hematite, a red ochre or iron oxide. This pigment has been used by humans since prehistoric times for decoration, cave paintings, and as a dye. In ancient Egypt, red ochre was used in cosmetics and in the famous red burial shrouds. The red ochre pigment was highly sought after and traded across many ancient civilizations.

In the Renaissance era, the pigment cinnabar which contains mercury was widely used by artists to create the bold red color. The Impressionists later pioneered new blends of red tones using other pigments such as madder lake, vermilion, and synthetic reds.

Wavelength and Visibility

In terms of physics, red light has the longest visible wavelengths of light in the color spectrum. It has wavelengths around 620-750 nanometers. Shorter wavelengths are not visible to the human eye. The long wavelengths of red mean that it scatters less when passing through dust and other particles. This makes red visible from very far distances and is why sunsets and sunrises often appear red.

Interestingly, red light is invisible to some animals. Bulls, for example, cannot see the red pigment, which is why matadors use a red cape. Other animals like dogs and cats cannot distinguish between red and green due to their dichromatic vision.

Primary Color

Red is considered one of the three traditional primary colors along with blue and yellow. By mixing primary colors, you can create all the other colors on the visible color spectrum. Red light combined with green light creates yellow light. Mixing red and blue makes purple.

As a primary color, red has a fundamental place on the color wheel. It features strongly in various color schemes and color psychology systems like the RYB (red, yellow, blue) model.

The prominence of the color red has also given rise to many idiomatic expressions and figures of speech in English:

  • “Red-handed” – being caught doing something wrong

These colorful expressions reflect red’s connections with danger, embarrassment, passion, anger, importance, and celebration.

Groups like the Red Army, Red Guards, and Red Brigades aligned themselves with red’s revolutionary symbolism. The color has a complex history of both positive and negative political associations.

On flags, red carries associations with courage and revolution. The flags of the Soviet Union, China, Vietnam and other socialist states feature red prominently. It is also used on the national flags of countries like Chile, Canada, and the United Kingdom.
