Charles Hayter's Colour Diagrams

AXIOMS.

First—That Yellow, Red, and Blue, are entire colours of themselves, and cannot be produced by the mixture of any other colours.–See Plate I.

Secondly—Yellow, Red, and Blue, contain the sole properties of producing all other colours whatsoever, as to colour, by mixtures arising entirely among themselves, without the aid of a fourth;–

Thirdly—Because, by mixing proper portions of the Three Primitives together, Black is obtained, providing for every possible degree of shadow.

Fourthly—And every practical degree of light is obtained by diluting any of the colours, as above producible ; or in oil-painting, by the mixture of white paint.

Fifthly—All transient or prismatic effects can be imitated with the Three Primitive Colours, as permanently considered, but only in the same degree of comparison as white bears to light.

Sixthly—There are no other materials, in which colour is found, that are possessed of any of the foregoing perfections.
