In this type of art, the forms of expression are many, and all can be “made to measure.” Which technique is right for us?
Watercolor is the most common technique, but also rather complicated, contrary to what one might believe. A technique in which experience will certainly guarantee excellent results. These are quick, light brushstrokes, where the choice of color is combined with different plays of color.
The technique has very ancient origins, experiencing considerable success during the eighteenth century in France and England. Watercolors are commercially available, generally in tubes, and must be diluted with water, not too much to compromise the chromatic result.
The effect of watercolor painting gives remarkable transparency. For this reason, if we decide to paint a pencil drawing, we check that the marks are very thin and light because once the paint is spread, it will no longer be possible to remove them. In this sense, the greater the technical knowledge, the fewer mistakes.
Through the oil paint, powder pigments are mixed with oils. In the past, olive oil was widespread, today flax oil. A highly innovative technique dating back to the Middle Ages was often used in a “mixed form” with tempera. Certain evidence of this technique’s use can be found in every way in the fourteenth century in Flanders; among the first artists to use them, the Flemings, among which Jan Van Eyck stands out.
It is the most modern form of painting, suitable for any type of surface. Acrylic colors have several positive aspects: they give brightness, transparency, brilliance, dry rather quickly, and are easily “assembled” together. They must also be diluted with water and are not subject to any risk from atmospheric agents or chemical changes.
The surfaces can be multiple (some of them must first be treated) and the colors. It is advisable to always equip ourselves, even in this case, with black and white. Since acrylics are waterproof, achieving particular shades can be a challenge. However, we could use a sponge or an old toothbrush to splash color and achieve different effects.
The Theory Of Colors
Johannes Itten, a famous painter, developed a real theory of color in the mid-1990s. We have said that we can obtain all the chromatic shades we want through mixing from the primary colors (red, yellow, blue). Let’s see how.
First of all, remember that by mixing the primary colors, we will get black.
The secondary colors that we obtain by mixing the primaries are orange (from the union of yellow and red), purple (from red and blue), and green (from yellow and blue).
The tertiaries are obtained from the union of a primary and a secondary color and represent nothing but the latter’s shade.
