Orange is a bold color that has been popular in society and art for centuries. As the balance between red and yellow, orange elicits strong, positive feelings of excitement while also signaling against danger. Read on for more information about the history and cultural meanings behind the color orange.

Facts About the Color Orange

Here are some facts about orange:

• The artist Vincent Van Gogh used a lot of orange in his paintings, mixing yellow and red to create unique shades.
• Orange is the color of safety equipment and prison jumpsuits because it’s highly visible.
• The orange color in fruits and vegetables comes from carotene.
• The shade of orange on the Golden Gate Bridge is “international orange,” which protects against rust from the ocean’s salt and moisture from the region’s fog.

A Look at the History of the Color Orange

The orange color was used in art in ancient cultures. Ancient Egyptians used the realgar mineral to create orange paint for their tombs, and orpiment was used in illuminated manuscripts during the Medieval period. The orpiment mineral was used to make orange pigment and was a popular trade item in Ancient Rome and a type of medicine in China.

The name “orange” was given to the color in the 16th century — it was called “saffron” or “yellow-red” previously. When Portuguese merchants brought orange trees to Europe from Asia in the late 15th and early 16th centuries, the citrus fruit’s name was adopted for the general color.

The Meaning of the Color Orange

Some cultures regard orange as a sacred color because it balances red’s power and yellow’s perfection. Monks and holy men in some Asian religions, like Buddhism, wear orange robes because that dye has been readily available historically. Buddhists also connect orange to the highest state of illumination. Orange is the color of transformation in Confucianism.

Green is the color of life, reflected in nature as a sign of renewal. As a bright, positive color, green has many cultural meanings in religion and art. Read on for more history, meanings and facts about this hue.

Facts About the Color Green

Here are some facts about the color green:

• The name “green” is related to the Old English word “grene,” the term for the color of living plants.
• Historians think that Napoleon Bonaparte died because of Scheele’s Green. This toxic pigment was in his green bedroom wallpaper.
• Since green evokes calmness and serenity, architects and designers often implement the color in environments like hospitals.
• In the Elizabethan era, green was a common color for wedding gowns for brides in the lower and middle classes.

The History of the Color Green

Green has been used in art since the time of the Ancient Egyptians. They used green earth and malachite, while the Ancient Greeks used verdigris. Green had a resurgence in art during the Impressionist movement due to advancements in green pigments and paints. The bold emerald green became popular in fashion in the 1800s, used for gloves and dresses.

Understanding the Meaning of the Color Green

Green is associated with nature since it is the color of chlorophyll, a pigment in plants. Because of this connection, green is used for environmental activism — products and actions that protect the environment are “green,” and people with a talent for growing plants have a “green thumb.”

In Ancient Egypt, green was a symbol of rebirth and regeneration. Green is sacred in Islam as it is connected to the Prophet Muhammad.

Blue is the color of the sky and water, symbolizing peace and serenity. Though the color is one of the most recently recognized, it’s popular in culture and fashion. Read on for more about the color blue.

Facts About the Color Blue

Here are some facts about blue:

• Blue was the last color to be coined as a term in the English language.
• Blue is infrequent in nature, so blue flowers are created from genetic modification and breeding.
• The idea of blue as the color for boys began after World War II. Manufacturers wanted to sell more clothes by making separate clothing for boys and girls.
• The pigment Prussian blue creates perfect copies of drawings. Architects use this hue to copy their designs, which is where the term “blueprints” came from.

A Brief History of the Color Blue

Due to blue’s rarity in nature, it has a shorter history than other colors. Blue is not present in cave paintings from 20,000 years ago, and the Ancient Greeks did not have a term for blue. Ancient Egyptians valued the blue semiprecious stone Lapis lazuli, so blue became common in their language and clothing.

Though blue was worn mainly by royalty for many centuries, it became a more common color in 431 AD. The Catholic Church depicted the Virgin Mary in a blue robe, adding a positive meaning to the color.

The Meaning of the Color Blue

The color blue symbolizes confidence and authority that is noninvasive and objective. Unlike red, blue is nonthreatening, fostering peace, dependability and security. Since the color produces a slow physiological response, blue is also the color of creativity. Light blue shades improve concentration, and dark blue hues improve thought processes.

Spectrophotometry vs. Spectroscopy

Spectrophotometry and spectroscopy are undoubtedly similar words — however, these terms are not interchangeable. While spectrophotometry and spectroscopy deal with related concepts, they focus on different scientific interactions and outcomes to gain varying insights.

Through this guide, you’ll learn about the difference between spectrophotometry and spectroscopy, their basic definitions and the instruments used in each science.

What Is Spectrophotometry?

Spectrophotometry operates on the principle that every chemical compound absorbs, reflects or transmits light over a specific wavelength spectrum. You can use this technique to determine the amount of light a chemical substance absorbs by measuring the intensity of the light as a beam passes through the sample.

The science of spectrophotometry allows for qualitative and quantitative analysis and is widely used across various industries, including chemistry, physics, biochemistry, biology and clinical studies.

Through forensic spectrophotometry, analysts can intensely study crime scene evidence using the power of electromagnetic imaging. Spectrophotometry is the process of scientifically and objectively measuring color and radio wavelengths. It is more dependable than using human eyes, and it provides reproducible results on an easy-to-understand scale. With spectrophotometry, forensic examiners can distinguish between the chemical composition, material and even brand of a piece of evidence all by examining how the sample reflects wavelengths. 

Spectrophotometry is a preferred method of forensic analysis due to its non-destructive analytical abilities. This process is versatile enough to analyze fibers, hairs and forensic materials such as bodily fluids, drugs and fingerprints. Spectrophotometers also have the advantage of not requiring sample preparation before a material can be analyzed. 

What Is Spectrophotometry?

Spectrophotometry refers to the process of analyzing samples using electromagnetic waves. To test a sample, spectrophotometers test how the light refracts and reflects off a particular material and analyze its color, infrared and ultraviolet properties and more. Using spectrophotometry, you can tell the difference between similar samples of hairs, fibers, drugs, bodily fluids and fingerprints. 

Spectrophotometry works by taking a sample and measuring the intensity of light when a beam passes through it. Since each compound transmits and absorbs light differently, it is possible to identify the true nature of a substance by analyzing this wavelength. Depending on the nature of the sample, it can be studied using either a UV-visible or infrared range spectrophotometer.
