Chapter XVI: Part THE SECOND

ON THE APPLICATION OF THE LAW OF SIMULTANEOUS CONTRAST OF COLOURS.

INTRODUCTION.

120. Before entering into the details of these applications, I think it necessary to offer some considerations which will enable me to establish some propositions or principles, to which I shall have frequent occasion to refer. I propose to give—

121. 1. Definitions of several expressions applicable to colours and their modifications. 2. The means of representing and defining colours and their modifications by the aid of diagrams. 3. A classification of the harmonies of colours. 4. A view of some arrangements of the primary colours with white, black, and grey.
