We cannot paint and decorate with light rays and color reflections from the spectrum of the rainbow, raindrops or a glass prism, as described in Chapter I.

Man has therefore searched out material substances from the soil, mines and vegetation, through his ingenuity in manufacturing and chemistry, to match the colors he sees in the spectrum. What these color substances are should next concern one who is anxious to become skilled in color mixing and use.

The number of shades of a single color found upon the market today is legion;—the siennas, umbers, venetian and Indian reds, chrome yellows and ochres varying in shades depending upon what part of the world they come from, upon manufacturing, chemical, grading and toning processes employed in their production.

These differences also have a bearing on prices charged for colors. The matter of price is always relative as to colors; care must be exercised in buying and in using them. Each grade of colors is made for certain purposes and it is wasteful or disappointing to use them indiscriminately; for instance, the use of a low-priced grade of tinting colors for rough barn painting may prove satisfactory and economical, but such colors certainly would prove disappointing if used on fine interior decorating. And the use of decorators' or artists' colors for rough work would certainly prove expensive and wasteful.
