Orange, however, seems to be the only basic color word for which no other word exists in English. There is only orange, and the name comes from the fruit. […]
This is not to say that no one recognized the color, only that there was no specific name for it. In Geoffrey Chaucer’s “Nun’s Priest’s Tale,” the rooster Chaunticleer dreams of a threatening fox invading the barnyard, whose “color was betwixe yelow and reed.” The fox was orange, but in the 1390s Chaucer didn’t have a word for it. He had to mix it verbally. He wasn’t the first to do so. In Old English, the form of the language spoken between the 5th and 12th centuries, well before Chaucer’s Middle English, there was a word geoluhread (yellow-red). Orange could be seen, but the compound was the only word there was for it in English for almost 1,000 years.
