Colors Challenge – 13 Colors You’ve Probably Never Heard Of Before

If you’re one of those people who think they already know everything about colors, you’re about to be proved wrong. Sure, everyone learns the colors of a rainbow when they’re young – red, yellow, orange, indigo, blue, violet and green – but you’d be surprised to know there are other weird colors out there that you haven’t even heard of.

Even though it is likely that you have actually come across these obscure colors before, you would have mistaken them for a common color shade. So that favorite fuchsia scarf of yours might actually be of a color called amaranth, or that rubbery toy duck isn’t exactly yellow, but aureolin! If you’re already puzzled hearing the name of these obscure colors, read on to find about thirteen other strange colors on the RGB chart that you might have never read about anywhere.



Believed to have first used in China in the early fourth century B.C, vermilion slowly reached the shores of Europe and was used extensively in the paintings during the Renaissance. This strikingly beautiful combination of orange-red pigment is made up of 89% red, 20.4 percent blue, and 25.9 percent green according to the classification that RGB color chart uses. Vermilion is also known as cinnabar in some countries.




This shade of red-pink takes its inspiration from the flowers of the amaranth plant. On the RGB color chart, it has 89.8 percent red, 31.4 percent blue, and 16.9 percent green.




Gamboge on the RGB color chart has 89.4 percent red and 60.8 percent green, along with a slight tinge of blue (5.9 percent). Gamboge is actually a gum resin that is collected from tree trunks, and dates back to the early 17th century Europe. A 2017 study notes that the slight tinge of mustard yellow color is extracted from Garcinia trees bark, and it was predominantly used as a dyeing agent on robes of Buddhist monks back then.




The name “coquelicot” originally came from the French language, which meant “wild corn poppy” as it was known for its bright colored red-orange hue. The term was adopted by the English language to describe colors that looked like poppy, and comprises 100 percent red, no blue, and 22 percent green on the RGB color chart.




Burlywood is a light shade of brown – quite similar to khakis – and derives its name from a similar colored wood. Burlywood is quite a balanced color on the RGB color chart, with 87.1 percent red, 52.9 percent blue, and 72.2 percent green.




First of all, can we all agree to the fact that celadon is indeed a truly beautiful color. And it has always been considered a very special color. In fact, it was once reserved only for the royals, who wore it on the special occasions. This pale green hue is a shade of 67.5 percent red, 68.6 percent blue, and 88.2 percent green on the RGB color chart.




You might have heard of aureolin if you’re a painter, as it is extensively used in painting. Aureolin is a straw, transparent, ochre like yellow hue with a rich greenish undertone, according to Michael Harding, an oil paint company. The color is quite similar to how cobalt yellow looks, and was produced for the first time in the early 1850s to replace gamboge, which apparently earned a bad name after the sap after which it was named started affecting people’s health adversely.




RGB color chart has glaucous as a color with 71.4 percent blue, 51 percent green, and 37.6 percent red. And if you look at this color, you would realize that it looks something like a wintry mix, and so it doesn’t really surprise us that the term “glaucous” literally translates to “having waxy or powdery coating that gives a wintry appearance”.




Skobeloff is a color that resembles teal to quite an extent, so if you come across a teal colored product next time, it might not actually be teal, but skobeloff instead. Skobeloff is a blend of green and blue in equal proportions (45.5 percent eact) with no red in the RGB color chart.




Another color that is based on blue-green hue, viridian also has a tinge of red in it; it has 25.1 percent red, 42.7 percent blue, and 51 percent green.

If you’ve learned the Latin, you’ll realize that the color derives its name from the word “viridis”, which means “green” in Latin. Or, if you’ve seen the 1988 movie called Beetlejuice, you would know about this color from the scene where the characters mention it when they talk of remodeling Deetz’s house.



Mountbatten Pink

While Mountbatten pink can be passed off as pink in technical terms, it does look more like a purple in the true sense. That is mainly because of the strong presence of red (60 percent) along with blue (55.3 percent) that is has, along with 47.8 percent green.

According to a book titled Great Personalities of the World, Lord Mountbatten used this color extensively to color the British Royal Navy ships during the World War II.




If you are of the opinion that a combination of green-gray looks something that what you’d commonly see on a military uniform, you aren’t exactly wrong. During the World War I, feldgrau was used by the German military as the official color. Feldgrau has 30.2 percent red, 32.5 percent blue, and 36.5 percent green on the RGB color chart.




A hue of violet, phlox is actually devoid of color green, and only has red (87.5 percent) and blue (100 percent) on the RGB color chart. The name “phlox” is derived from the plant phlox, which has flowers of the same color, and is mostly found in the North America.
