Theory of Color

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. There is one point, however, which I should here like to dwell upon somewhat more at length, i. E. The choice of terms for the designation of some of the colors. Peculiar difficulties had to be overcome in this respect, even in the German language, since several of the names, which are familiar to the physicist, are entirely unknown to the artist, while dyers and weavers employ still other designations, which are again different from those used by either of the two classes first named. I therefore resolved to depart from the usages of physical terminology in a few instances in which this terminology would be likely to give rise to decided misunderstandings, and I cannot refrain from expressing a strong hope, that these changes may be sanctioned and adopted by my colleagues in the profession. It seems well, at all events, to call attention to these changes here, and to give a concise statement of the reasons which induced them.
