The colors of the rainbow make the color wheel seem simple— a couple reds, purples, blues and greens and you’re on your way. However, the color spectrum is actually a vast and complex beast. The human eye can only see a fraction of the colors on earth and, of those, we aren’t familiar with all of them. Scientists are also constantly innovating colors for a variety of applications, such as space travel and exploration.

Glaucous describes a blend of green and blue— the kind of color that starts debates about which one it truly is. The term glaucous, which is etymologically related to the word glaucoma, comes from ancient Greek. The famous philosopher Homer used the term glaukos to refer to water, leaves, honey and eyes. Rather than a single color, the original term referred to an object’s ability to glisten or shine. Over the years, as language developed to include specific terms for colors, glaukos became glaucous and started to refer to blue-green colors. Since glaucous is archaic, it’s difficult to find accurate representations of the color today.
Did you know
Glaucous also refers to the waxy protective coating that fruits like apples naturally develop.

Take a trip to the Swedish countryside and you’ll notice that most of the cottages are the same shade of bright red. This particular shade is falu red, termed such because the color comes from the Falun Copper Mine in Sweden. It’s a waste byproduct of the mining process that rusts over time. Washing, drying and burning these rusted over ores creates the unique pigment. The temperature in which the byproduct is heated changes the shade. Higher temperatures result in darker pigment.
Did you know
The Falun copper mine has been around since the ninth century and was one of Sweden’s greatest income sources until the seventeenth century.

Stuart Semple’s self proclaimed “pinkest pink” is the result of art world controversy. After the creation and subsequent development of a usable vantablack, another color on this list, the company that invented the technology exclusively licensed it to an artist named Anish Kapoor. Other artists were upset that this color was being kept from them and one, named Stuart Semple, decided to respond in turn. Semple created the pinkest pink pigment and made it available to everyone except Kapoor. Kapoor got his hands on it anyway, posting a picture to Instagram with his middle finger dipped in the vibrant pigment.

Vantablack is known as the darkest man made pigment. The color, which absorbs almost 100 percent of visible light, was invented by Surrey Nanosystems for space exploration purposes. The special production process and unavailability of vantablack to the general public makes it the rarest color ever. It now exists as a coating used in deep space imaging, automotive sensing, optical systems, and art. Some of its most notable properties include ultra low reflectance, UV absorption, and high thermal shock resistance. Vantablack’s visual effect is quite striking. Rather than a painted surface, objects coated in vantablack look two dimensional.
Did you know
Vantablack absorbs so much light that no spectrometer can accurately determine what percentage it actually takes in.
