THE LAWS OF HARMONIOUS COLOURING ADAPTED TO INTERIOR DECORATIONS.

_From the Atlas._

Every line of this useful book shews that the author has contrived to intellectualise his subject in a very interesting manner. The principles of harmony in colour as applied to decorative purposes, are explained and enforced in a lucid and practical style, and the relations of the various tints and shades to each other, so as to produce a harmonious result, are descanted upon most satisfactorily and originally.

_From the Edinburgh Review._

In so far as we know, Mr Hay is the first and only modern artist who has entered upon the study of these subjects without the trammels of prejudice and authority. Setting aside the ordinances of fashion, as well as the dicta of speculation, he has sought the foundation of his profession in the properties of light, and in the laws of visual sensation, by which these properties are recognised and modified. The truths to which he has appealed are fundamental and irrefragable.

_From the Athenæum._

We have regarded, and do still regard, the production of Mr Hay’s works as a remarkable psychological phenomenon—one which is instructive both for the philosopher and the critic to study with care and interest, not unmingled with respect. We see how his mind has been gradually guided by Nature herself out of one track, and into another, and ever and anon leading him to some vein of the beautiful and true, hitherto unworked.
