Some years ago the writer encountered a reference to a certain spectral line which was there characterized as "blue," whereas I should without hesitation have called it violet. This suggested the question as to whether the common names of pure colors had ever been defined as to their wave length boundaries, and a surprising lack of agreement on the subject was shortly disclosed. For example, there appear in the literature the following designations of spectral color boundaries, in Angstrom units, incidentally with no indication as to how they were arrived at.
