  Colour as a Means of Art Being an Adaption of the Experience of Professors to the Practice of Amateurs

summary:
  Although Harmony or Pictorial Colouring does not _depend_ upon any _particular_ quantities or arrangement of _particular_ tints, as the slightest consideration of the infinite variety of Pictures that have been produced will prove; certain quantities and arrangements of certain colours, have been found to effect it. The definition of a PEARLY HUE, as obtained by softening or blending the _warm_ colours without adulterating one with the other, is equally liable to objection as untrue.

summary:
  The use of rotating color disks on the wheel and the top by which an infinite variety of intermediate hues can be made and accurately named by the pupils reduces the required number of papers to those types necessary for first primary work, and thus prepares the child for the use of pigments at an earlier age than would be possible without such color instruction. After having accepted this fiction as a scientific theory for so many years, it is very difficult to convince the artists and colorists that in it all there is nothing of value to any one, but such is practically a fact, because from no three pigmentary effects in red, yellow and blue can the three colors orange, green and purple of corresponding purity be produced, neither are the primary colors complementary to the secondaries as claimed nor are the so-called tertiaries new and distinct colors but simply gray spectrum colors.

summary:
  Thus composed is the _citrine_ colour of fruit and foliage, on inspecting which we distinctly trace the stipplings of orange and green, or of yellow, red, and green. Growing deeper by age has been attributed to ultramarine; but it is only such specimens as would acquire depth in the fire that could be subject to the change; and it has been reasonably supposed that in pictures wherein other colours have faded, it may have taken this appearance by contrast.

summary:
  For not remembring at present many of those other Trials, long since made to satisfie my self about Particulars, and not having now the Opportunity to repeat them, I must content my Self to have given you the Hint, and the ways of prosecuting the search your Self; and only declare to you in general, that, As I have made many Trials, unmention'd in this Treatise, whose Events were agreeable to those mention'd in the twenty fifth Experiment, so (to name now no other Instances) what I have try'd with Acid and Sulphureous Salts upon the Pulp of Juniper Berries, rubb'd upon White Paper, inclines me to think, That among that vast Multitude, and strange Variety of Plants that adorn the face of the Earth, perhaps many other Vegetables may be found, on which such _Menstruums_ may not have such Operations, as upon the Juice of Violets, Pease-blossoms, & We have sometimes had the Curiosity to try what Colours Minerals, as Tinglass, Antimony, Spelter, &c. would yield in several _Menstruums_, nor have we forborn to try the Colours of stones, of which that famous one, (which _Helmont_ calls _Paracelsus's Ludus_) though it be digg'd out of the Earth and seem a true stone, has afforded in _Menstruums_ capable to dissolve so solid a stone, sometimes a Yellowish, sometimes a Red solution of both which I can show you.
