Indigo and blue -- how color definitions have changed

New York, NY
Post #: 753
The traditional colors of the rainbow, as originally named by Isaac Newton back in the 1660's, are Red, Orange, Yellow, Green, Blue, Indigo, and Violet.

However, it turns out that what Newton meant by "Blue" and "Indigo" are different from the meanings commonly given to those color names today. What he called "Indigo" is known today as (deep) blue, whereas what he called "Blue" is known today as aqua, cyan, or greenish-blue. The word "indigo" as a color name is, itself, derived from indigo dye, which is a deep blue dye traditionally used in blue jeans, for example.

This is discussed in the Wikipedia article on Indigo. (See especially the section on Classification as a spectral color.)

interesting, i use color associations in magick alot. Common ones are green - money and so on. the purple/violet spectrum is likely more interesting than the blue in its abilities.
