The Standardisation of Colours

Abstract

UNDER the title of “International Rules for the Specification of Colours,” Mr. Hans-Jacob M-ouml;ller has reprinted an essay by him from the Journal of the Danish Apothecaries' Association (Archly for Pharmaci og Chemi, November 14, 1910) showing the importance of having an international scheme of colours so as to enable reference to be made to a definite tint on a definite scale, and recommending as the most useful and most practical scheme of the kind that drawn up by Klincksieck and Valette, a scheme based upon the original system drawn up by Chevreul. There can be no doubt that such a colour scheme, recognised throughout the scientific world, would be of great practical value. For example, to take a very obvious instance, a large number of chemical reactions in connection with organic substances, such as dye-stuffs, depend upon colour changes, and if it was possible to describe these colour changes in accurate language, it would be of great practical value to the chemist.
