THE PRINCIPLES OF BEAUTY IN COLOURING SYSTEMATISED.

_From the Spectator._

In this new analysis of the harmonies of colour, Mr Hay has performed the useful service of tracing to the operation of certain fixed principles the sources of beauty in particular combinations of hues and tints; so that artists may, by the aid of this book, produce, with mathematical certainty, the richest effects, hitherto attainable by genius alone. Mr Hay has reduced this branch of art to a perfect system, and proved that an offence against good taste in respect to combinations of colour is, in effect, a violation of natural laws.
