Orange (red-yellow) is a tertiary color. Most tertiary colors are named for things.
Chartreuse (yellow-green) is named for a liquor and was first used in 1764, much more recently than orange.
Azure (blue-cyan) is named for lapis-lazuli.
Rose (magenta-red) is named for the flower.
Turquoise (green-cyan) is named for the gem, with its etymology only in the 17th century.
Violet (magenta-blue) is actually unique in that it's the only tertiary color that isn't named for something. Its name comes from the proto-Indo-European word for purple. (In this case, purple is the color named for a thing).
The process continues for further subdivided color. Most quarternary colors don't have distinct well-accepted names, but some like scarlet, fuschia, and aquamarine are reasonably accepted.
If you've gotten through life calling things yellow-green instead of using the word chartreuse, you know how people got through life without using the word orange.
