Ruby (color)

Ruby is a bright red or pink color. It looks like a shiny, cut stone. A small bird has a ruby neck. This bird nests in North America. A sea fish also has this name. It lives near Australia. Some red light looks like this color too. It can even look a bit purple. Ruby is a very special color to see.

Ruby is a shade of red or pink. It gets its name from a ruby gemstone. People cut and polish these stones to make them shine. The name for this color first appeared in English in 1572.

Many different types of ruby colors exist. There is a dark tone called antique ruby. This name was first used in 1926. There is also a color called medium ruby. Crayola crayons use this name in a special set. In 2001, Crayola made a metallic color called big dip o'ruby.

We can see this color in nature, too. A small bird is called the ruby-throated hummingbird. It is the only hummingbird that nests east of the Mississippi River. In the ocean, a fish called the ruby seadragon lives near Australia. This fish was found in 2015. It was the first new seadragon found in 150 years. Another fish, the ruby snapper, also lives in Australia. Even light can look ruby red. This happens with infrared light. Some of this light can look a bit purple.

Ruby is a beautiful color name. It represents the shade of a cut and polished ruby gemstone. This color is a shade of red or pink. People use this name to describe many different things. It helps us talk about specific shades in art and nature.

There are many different ways to name this color. Some shades are very dark, like antique ruby. The name antique ruby first appeared in English in 1926. Other shades are lighter, like medium ruby. Crayola uses this name for a crayon in a 1994 set. There is also a shiny version called big dip o'ruby. This metallic color came from a Crayola set made in 2001.

History shows us how these color names grew. The first use of the word ruby as a color was in 1572. Many systems help people match colors exactly. The RAL system in Europe started in 1927. It reached its current form in 1961. The British Standards 381 list also names a deep ruby. This list was first made in 1930 and updated in 1955.

Nature also uses this lovely color. The ruby-throated hummingbird is a small bird. It is the only hummingbird that nests east of the Mississippi River. In the ocean, a fish called the ruby seadragon lives near Australia. Scientists first described this fish in 2015. It was the first new seadragon found in 150 years. Another fish, the ruby snapper, also lives in Australia.

Even light can show us ruby red. This happens with a type of light called infrared. Humans can see some of this light up to 1050 nanometers. At 660 nanometers, the light starts to look slightly purple. As the wavelength grows, it looks even more purple. Below 900 nanometers, the color looks very much like purple. This shows how light and color work together.

Ruby is a specific color name used to describe a shade of red or pink. This color is meant to represent the appearance of a cut and polished ruby gemstone. Because colors can vary, many different versions of ruby exist in art and science. People use these specific names to communicate exact shades in different industries. These shades can range from bright pinkish tones to very dark reds.

Color naming often follows specific systems to ensure accuracy. One such system is the RAL color matching system used widely in Europe. This system helps people identify and use the exact same color in different places. The RAL color list first originated in 1927. It eventually reached its present form in 1961. Another important system is the British Standards 381 color list. This list is used for special purposes like coding and identification. It was first formulated in 1930 and reached its final form in 1955. In this list, a deep tone of ruby is identified as #542.

There are many distinct variations of the ruby color. Some names describe the brightness or the texture of the shade. For example, medium ruby is a specific color used by the Crayola company. This color was introduced in 1994 as part of the Gem Tones specialty crayon set. Another variation is big dip o'ruby, which belongs to the Metallic FX set. Crayola formulated these metallic colors in 2001. While it is meant to look metallic, computer screens cannot actually display metallic effects on a flat surface.

Other names describe the darkness or tone of the red. Antique ruby is a dark tone of the ruby color. The first recorded use of the name antique ruby in English was in 1926. There are also other specific shades like rubine red and ruber. These names allow artists and designers to be very precise.

History shows us how long humans have used this name. The first recorded use of ruby as a color name in the English language was in 1572. This shows that the concept of a ruby-colored shade has been part of our language for centuries. Since then, the way we categorize these colors has become much more scientific. We have moved from simple descriptions to complex digital and industrial standards.

Nature also provides beautiful examples of this color. The ruby-throated hummingbird, or Archilochus colubris, is a small bird. It is unique because it is the only hummingbird species that regularly nests east of the Mississippi River in North America. In the ocean, the ruby seadragon lives along the coast of Western Australia. This fish belongs to the Syngnathidae family, which includes seahorses. Scientists first described this species in 2015. It was the first new seadragon discovered in 150 years. The ruby snapper is another fish that lives in Australia.

Even the physics of light relates to the ruby color. Humans can see a portion of the infrared spectrum. This light is visible to us up to approximately 1050 nanometers. In this part of the spectrum, the light appears ruby red. However, the color changes as the wavelength increases. Starting at about 660 nm in the visible red, a monochromatic source like a laser begins to look slightly purplish. Below about 900 nm, the color looks more purple than red. This connection shows how light wavelengths determine the colors we perceive.
