The prevailing colors are Blue, Drab, Grey, Straw, Buff, Olive and Stone Colors.
A yellowish tint, you will find, produces the best results.
Mounting the Picture. Before commencing upon the drawing it must be mounted upon a stretcher, after which, with a firm crayon, trace the outlines, with either red, brown, or grey color. The beginner will find the Pentagraph of excellent service for outlining where you are working from a copy.
Sketching in the Outlines. This must be done lightly, in order that the crayon does not enter into the texture of the paper, so as to render the marks difficult to be superseded subsequently by the necessary colors. When the outline is completed, the breadths are made out by means of a brown crayon, and a stump, working for the degrees of shade.
Applying the Crayon. When the likeness is satisfactory in the sketch, the complexion may be commenced on, beginning with the lights. The whites, yellows, reds and greys must be worked in, and blended to an imitation of the reality of nature. From the highest lights, proceed in regular order to the deepest shades, and, in order to secure substance, these must be put in equal in strength to nature; after which the middle tones must be carefully blended, so as to unite the lights and shades by imperceptible gradations. The markings must be definitely made out, and the reflexes also, if there be any. As the fresher tints occur principally in the lights, it would be well to keep the color rather high, and of a warm tone, in order to reserve the brightest and most effective tints till the last.
When all the tints have been laid in, and the head is in a satisfactory state as to form, color and expression, then, with the finger, pass over the whole, working and blending the colors in harmony. In this operation the finger is used instead of a stump, and nothing else will answer better. When this operation is concluded, the crayons will be again used to bring up the colors, and tone to those of the life—to modify and correct those which may require retouching.
Those parts which are heavy must be relieved, and those which may be too cold or too warm, must be reduced to harmony. Working with the finger will be found the most available method of managing the crayons.
Having laid in the tints, according to the natural complexion, it will be necessary, before touching the work with the finger or blender, to be certain that all are laid in the proper places; a little experience will enable you to judge; there remains but little work for the fingers to perform, and the less the colors are worked upon the more fresh and transparent they will remain.
Colors and the Composition of Tints. The shades of flesh tints are warm or cold, according to the warmth or coldness of the breadths of the light. If the lights be of a healthy hue, the shades may be warm, inclining to brown, mixed of various colors, broken with light red, carmine, yellow, blue or grey. Some artists represent nature as violet or green, in shade; but this is untrue and must be guarded against. It is advisable generally to follow the Italian feeling of leaving the dark passages warm. When the complexion is strong in color, the effect is most agreeable; if worked without hardness, opacity or blackness. In feminine portraits the work must be brought up to the utmost brilliancy of color, by the brightest and freshest hues, composed of White, Naples Yellow, Vermilion and Madder, mellowed with Yellows, or slightly purpled with Lake or Carmine, according to the prevalent tint of the subject. In the masculine subject the colors will be stronger, and the half-tints more positive. Great care must be observed, lest the high and delicate passages be soiled or stained. They must only be approached by, and blended with, other shades at their extremities; and these shades are, in most cases, half tints.
It will be clearly seen by the artist, that if the intermediate tint be too cold, it must be treated with the reds or yellow; if too warm, reduce by grey or blue. The lights and shades should be carefully graduated, and harmony prevail throughout the work.
