About the color Brown-Nose

A Japanese color with an English nickname

Brown-nose is another name for kobicha, and both use the same code, #6B4423. Kobicha is one of the traditional colors of Japan, used for dyes in kimono design. The English name Brown-nose shows up next to it in Wikipedia's list of brown shades.

The joke behind the nickname comes from the Japanese word. The Wikipedia article on kobicha says the name first meant the color of a kelp tea. Later the word was also used for a kind of flattery. That matches the English slang brown-nosing, which means sucking up to someone.

Using it

This is a dark orange brown, a bit warmer than coffee. White text on it has a contrast ratio of 8.48 to 1, so it reads well. For lighter and darker options, see the shades of brown.
