Excerpt from New Elucidation of Colours, Original Prismatic, and Material: Showing Their Concordance in Three Primitives, Yellow, Red, and Blue; And the Means of Producing, Measuring, and Mixing Them: With Some Observations on the Accuracy of Sir Isaac Newton Light is essential in colouring some things and bleaching others; and it was once a valuable secret, that to get the brightest carmine it should in the process of making be dried in the sun. Many chemical substances are changed by exposure to light; oils become whiter. Perhaps even this effect may be assisted with the help of a contrasting shade, that the actions may be more forcibly directed on the object. Light, on an object when seen refracted by the prlsm, shows its colours; which however do not affect the general local tint of the object which seems to re ect it, but rather depend upon the darks or shadows; and broad at masses of any coloured object do not appear changed excepting at the extremities, or where dark or shade seems to help to collect the coloured radii: thus it may be' possible to make broad tints or narrow ones with such proportions of dark or shade as may be suited for many purposes of the utmost utility in the arts, manufactures, agriculture, &c.
