Water Color: Water colors. These were the earliest type of brushwork pictures, and are made of pigments soluble in water. It was the method employed by the Chinese and Persians. The true water color is technically called an aquarelle, and is produced with a transparent color mixed with water. As the mixture is usually applied to white paper, the whiteness of the background affects the tonal value of the color and plays its part in the final effect. Aquarellists must work rapidly and surely, as it is difficult to alter a color when once it has dried. In gouache the pigment is first mixed with a white zinc powder to make it opaque. It is then thinned to the proper consistency with water and is applied to the paper or other background; but it is sufficiently opaque to completely cover the surface, so that only the pigment shows. Tempera, a very old process, is similar to gouache except that the pigment is combined with a thin glue or with white of egg instead of water. It is, today, extensively used in poster work, designs for magazine covers, and commercial advertising. Water color is used as a medium by itself and to color or tint drawings or engravings.
You can buy ready made colorwash paint, but you can alsocreati your own finish with latex or water-based eggshell paint and ati or pigment.
To prepare the surface of the wall, paint a base coat of mattei silk latex and allow to dry. Either choose the same color paint on color close in tone and mix a wash of latex and water, in equal parts. Gradually increase the water to make a thin color that willi run down the Wall in heavy droplets, but will allow the base color show through when it is applied. Once you have tested the washi a sample area, continue to apply the remaining color with awide brush using sweeping strokes. Further coats can be applied ina harmonizing color. For a more durable finish, you can use a • glaze as a wash over the whole surface. If you want a hard, protective finish, use a clear, matte polyurethane varnish, or. based acrylic varnish.See Also Expensive Color Portraits:One obviously excellent use for Flexichrome is in the pro¬duction of expensive color portraits. The Flexichrome proc¬ess has the advantage that it permits the photographer to make a number of black and white exposures in the ordinary manner and at the ordinary film cost, then have the selected negative carefully retouched before the print is made, result¬ing in a much more flattering picture than a straight portrait shot on regular color transparency film. Ordinarily, color re¬touching by any of the other processes can be done only by an expert and at great cost.
The art of Romney displays a certain fitfulness of achievement due partly to the instability of his character, and partly to his defective early training. His defects of technique are most ap¬parent in his historical and imaginative subjects; it is only when we examine his portraits, and especially his female portraits, that we find- that beauty of form and subtle charm of color which place him among the greatest portrait painters of the 18th century.
On The Other Hand See Various Color Phases:Spherical; deposited on leaves of food plants Larva (caterpillar): Occurs in various color phases; 2 extremes are bright green and black; in green phase ground color green; head and horn on tail yellow; little to each side of middle (stripe) line is row of pale spots outlined above and below with black; in black phase ground color black; head and horn on tail either yellow or orange; 3 yellow lines extend along back from horn to head; between these
2 extreme color phases is wide range of variations; grows to length of.
Drawings showing succes¬sive phases of action placed inside the drum and viewed through the slits were seen one after the other, so quickly that the images merged in the mind to produce the illu¬sion of motion. The editor wrote: "By such means it would be possible to see not only the successive motions of a trotting or running horse, but also the actual motions of the body and legs in passing through the different phases of the stride."
