Color me intrigued

Before the pantone: 10 color shades with old names

Colors come in a multitude of shades, most of them with a very specific name. Some of these names are a reference to a common object of that color —for example, ruby, maize, or lavender— while others, much more modern, are just a product of marketing, popular use, or just imagination —such as razzle dazzle rose, school bus yellow, or French blue. But some specific shade names have a story that goes back centuries, across different cultures and traditions. Here are ten color shades and the history behind their name.

This vibrant red-orange shade takes its name from an ancient pigment, highly toxic, made from cinnabar, a form of mercury. Its name comes from the Old French vermeillon, derived from vermiculus, a diminutive of the Latin vermis (‘worm’). What did this toxic pigment have to do with worms? An insect called Kermes vermilio was used to make a natural dye in a similar shade, but much more common than cinnabar, so its name became popular and was used for all similar red-orange shades.

Described as a shade that goes from light-brown to brownish-orange, tawny is associated with tanned leather, not only in color but in the origin of its name. Celts used tannum or crushed oak bark to treat animal hides and produce leather. Though Latin, this word made its way into Old French as tauné, ‘tan leather colored’, and then into English.

With a name that alludes to the sea, the origin of this deep blue shade seems to be quite straightforward, except it isn’t. Ultramarine blue takes its name from the Ultramarine pigment, made from grinding lapis lazuli stone. This pigment, as costly as gold, was imported from Afghanistan by Venetian merchants, who called it (azzurro) oltramarino or ‘(blue) from beyond the sea’.

Now described as cream or grayish yellow, ecru was initially used to describe the color of unbleached linen. Before bleached into a creamy white color, linen would retain the color of the dried flax fibers used to weave it. The French word écru, meaning ‘raw’ or ‘unbleached’, initially served as a mere descriptor of the fabric's state, but was eventually associated with its color.

To no one’s surprise, the name of this blueish-green shade comes from French. But although its French equivalent, vert-de-gris, means ‘green of gray’, there is no gray in its origin. There are two possible origins for this name: the first one is vert d'aigre or ‘green made with vinegar’, because a pigment of this name was made using copper and vinegar. The second one ties this shade to art objects imported from Greece, which gave way to the name vert-de-Grèce, ‘green of Greece’.

Indigo is used to describe a variety of blue shades, from the dark blue in the rainbow to various blue hues that can be achieved using indigo dye. Originally, the term indigo, from the Latin indicum (‘Indian’), was specifically used for a pigment made from the Indigofera plant and exported from India. Later on, the term became synonymous with the various blue shades resulting from that dye.

Nowadays, we automatically associate the color sepia with old photographs, but did you know its name and hue come from a fish? In ancient Greece and Rome, the ink of the sepia cuttlefish was used for writing, and it remained a commonly used drawing ink up until the early 19th century, when it started being used for watercolors and oil paints.

This one is tricky. As a color, auburn is a shade of brown, though it is often used to describe a specific type of red hair that has a mixture of red and brown tones. The term auburn, however, has nothing to do with red nor with brown. It comes from the French alborne, derived from the Latin alburnus or ‘off-white’, and it was used for blond people. How did it come to mean reddish-brown? Auburn and brown sounded similar.

Technically, there is no color named purpura in modern English, but there used to be. Made from crushed sea snails, the purpura dye was extremely expensive, and it became associated with royalty. Originally called porphura by the Greeks, the word was latinized as purpura, and was later adopted into English as purpul, from where we get the modern ‘purple’. So, while purpura is the original purple, it is nowadays called Tyrian or royal purple to avoid confusion.

This reddish-orange shade gets its name from the jasper, a semiprecious quartz known for having a pattern. The name ‘jasper’ comes from the Greek iaspis, meaning ‘spotted or speckled stone’. While there are multiple colors of jasper stones, the most common one is red, so the name of the stone became synonymous with that shade.

Decoding

Being a "treasured guest" is not a compliment. This is the hidden meaning

Have you ever heard "Code Adam" while shopping for groceries at Walmart? Or maybe you’ve heard how "Dr. Firestone" was being paged during a routine hospital visit. They sound like harmless announcements. But behind these ordinary words are secret codes staff use to signal emergencies without causing panic. From hospitals and supermarkets to airports and Disney Parks, these phrases quietly warn employees that something is happening. You hope you never hear them, but if you do, it helps to know exactly what they mean.

We all love getting special attention at airports or hotel desks, but if you hear the clerk call you a "treasured guest," don’t feel so flattered. You may not be as VIP as one could think.

In the hospitality industry, "treasured guest" has become a humorous bit of industry folklore to describe someone causing trouble. Maybe a customer yelling at staff over expired coupons, demanding impossible accommodations, or throwing a full-blown tantrum at the front desk. Whatever it is, the phrase has become the staff’s secret way to warn co-workers without escalating the situation in front of the customers. Most guests don’t realize the meaning, but once you know it, you may start hearing it more often. We just hope it’s not about you.

Imagine you’re pushing a shopping cart through Walmart when suddenly the overhead speaker announces, "Code Adam." You can easily assume it’s some kind of employee meeting or cleanup request. But when you see them start locking the exits and moving around, you know something’s wrong.

This code was created in 1994 by Walmart in collaboration with the National Center for Missing & Exploited Children (NCMEC), in memory of the tragic case of 6-year-old Adam Walsh. Adam was abducted from a Sears department store in 1981 while shopping with his mother. His father, John Walsh, later became famous for hosting the TV program America’s Most Wanted and advocating for missing children. Even if Adam’s story ended in tragedy, Walmart created the emergency system in Adam’s memory, and other retailers soon adopted it nationwide, intending to have a quick response to missing or abducted children.

You’re sitting in a hospital waiting room during a routine check-up when you suddenly hear "Code Blue, Room 214." Most people immediately know it sounds serious, even if they are not entirely sure why.

The phrase "Code Blue" is used at hospitals to draw the necessary staff and equipment to perform a resuscitation. It was created in the early 1960s at Beathany Medical Center by Dr. Hughes Day. Before then, hospital resuscitations were often chaotic and poorly coordinated. In 1961, Dr. Day received a grant to build one of America’s first cardiac care centers, and he developed both the Code Blue alert system and the modern crash cart to improve survival rates during cardiac emergencies. Today, the system is used in hospitals across the country, sometimes with specialized versions like "Code Blue Pediatric" or "Code Blue Neonate."

Imagine visiting a loved one in the hospital when the intercom calmly announces, "Paging Dr. Firectone to the third floor." Your head surely goes, "Dr. Firestone’s probably having a busy day up there." He is, but it’s not what you think.

The phrase is actually a discreet fire alert used to warn staff about smoke, flames, or overheating equipment without frightening patients and visitors. Hospitals adopted these coded announcements after realizing that openly yelling "fire" over loudspeakers could create panic, especially among patients who aren’t able to move quickly. "Code Red" is an alternative used by many health centers today, but it also hints at the situation while keeping hallways calm.

You’re standing at a checkout counter when the cashier picks up the phone and quietly says, "I need a Code 10 authorization." If you think that’s just another way to get a supervisor’s approval or technical issue, think again. In reality, the cashier may suspect the credit card is stolen or fraudulent.

Code 10 was developed through a cooperative effort between major credit card companies like Visa and Mastercard, along with international standard organizations. As credit cards became more common in the 1960s and 1970s, stores needed a discreet way to alert banks about suspicious activity without directly accusing customers and potentially putting employees at danger. When a cashier requests a Code 10, the bank’s operator begins asking yes-or-no questions to assess the situation and guide the employee on what to do next.

You’ve probably experienced those long airport security lines. The wait is usually uneventful. But sometimes, you can hear "Code Bravo" over the speakers. Maybe it’s a delay, or maybe it’s an issue with luggage. Within seconds, people stop moving, the security line freezes, and exits may even close. It’s something bigger.

Code Bravo is the emergency phrase used by airport security and the Transportation Security Administration to signal a serious security threat, such as an unattended bag, a breach at a checkpoint, or someone slipping into a restricted area. The term comes from the international phonetic alphabet used in aviation and military communications, where "Bravo" represents the letter B. When this is called, security staff immediately lock down affected areas, stop screening lines, and search for the source of the threat. To passengers, it’s sudden and confusing, but to security, it’s a carefully rehearsed response.

You are heading back to your cabin on a cruise ship when the speakers announce, "Code Alpha, Deck 7." You may think Alpha is related to the captain, but that’s not the case. It means someone on board is suffering a medical emergency.

The phrase comes from the NATO phonetic alphabet, where "Alpha" represents the letter A. In maritime emergency jargon, it became shorthand for a Priority A medical situation requiring immediate response. Cruise lines such as Royal Caribbean and Disney Cruise Line commonly use the term, though some ships use variations like repeating "Alpha" three times. Once the code is announced, onboard medical teams rush toward the specified deck or cabin. If necessary, stretcher crews are mobilized, and in severe cases, the ship may even divert course toward the nearest port for emergency evacuation. Passengers are enjoying the views, but the staff is running to save a life.

Anyone who remembers the CB radio craze of the 1970s probably smiles when they hear "10-4." Movies, truckers, and radio fans turned those number codes into a part of American culture. So if you overhear "10-33" on a police scanner, you might assume it’s just another routine message. But it’s not as simple as it sounds.

The 10-code system was first created in 1937 by Illinois State Police communications director Charles Hopper and later standardized by the Association of Public Safety Communications Officials, better known as APCO. Officers needed short phrases they could understand clearly over crackling radio signals. The 10-33 code commonly means an officer needs emergency assistance. In some departments, it also signals radio silence so dispatchers can focus on the crisis unfolding in real time.

Disney World is amazing, the parks offer something for everyone, and there are things to see wherever you look. But that’s exactly the kind of place where a child can easily disappear into a sea of strollers, balloons, characters, and crowds. For that reason, Disney has developed the "Signal 70," which alerts cast members and security that a child has become separated from their family.

The number comes from older police and emergency radio systems, where "70" was commonly associated with missing persons. Disney adopted the phrase because it allows employees to communicate discreetly without frightening or alarming nearby guests. If a member finds the child, they gently -and magically- escort them to Baby Care Center, where they coordinate the reunion.

Cruises are great to relax, enjoying a good book under the sun with a nice drink by the side. Until you hear "Echo, echo, echo" on the speakers. If you do, something is happening somewhere else on the ship.

The code is used among cruise employees to signal that dangerous winds or a navigational hazard are affecting the ship. It comes from the international maritime phonetic alphabet, where "Echo" stands for the letter E. In maritime signalling, the letter traditionally means "I am altering my course to starboard." And, in time, the phrase became associated with urgent ship maneuvers and weather-related warnings. However urgent, the repetition of the word by three doesn’t represent life-threatening situations. It alerts the crew of a certain hazard to prepare while avoiding panic among passengers.
