It is better to know the basic techniques and colors to paint successfully. A good knowledge of these techniques can have a good time and to paint at their respective levels.
The oil painting is a mixture of pigment and drying oil to obtain a more or less consistent. This paint dries more slowly than the acrylic paint and allow to better blend the colors together.
DRYING:
Rather, it is called hardening of the paint because it is an oxidation of the oil that polymerizes. Consider a chain reaction that can bind to molecules gradually, it hardens without changing the appearance of the work. The pigments then being imprisoned, this chemical reaction allows preservation of the work.
The support that we chose to be nurtured by successive layers of increasingly fat. The layers are thin little time to dry. (Otherwise, these layers would conflict with earlier if they were fatter, they would drag to oxidize and turn produce a phenomenon ranging from orange peel and that of the reptile in the molt) .
COLORS:
SOME INFORMATION CONTAINED ON THE TUBES OF PAINT (by manufacturer):
symbols on the tubes of color indicate the fixity full light or not. (Examples of symbols encountered)
-The letter "M" means: color mixture which is stable.
-A square white color transparent, it can be used to run glaze.
-A square black opaque color. A semi-
square black and white: color mid-transparent, semi-opaque.
-series indicates the price.
-Three stars: colors of a very degraded even complete fixity.
Two-stars: very strong color.
-Star: pure solid colors used.
The permanence of pigment reflects its resistance to change as a result of exposure to light and especially ultraviolet light, it will be preferable to refer to the chart of each brand, to determine his choice of color according to this criterion, but also its taste and its subject.
Colors can be of varying quality, fine, extra fine.
Extra-fine, they contain a high degree of pigmentation and finer grinding.
Some are more or less pendulous, transparent ...
The coverage depends on the chemical nature of the pigment, its particle size.
As for tinting, also called "degraded" is the ability to change by mixing the shade of another color or simply a white coloring.
For a tone needs less color, the better the dye is high
TONE, STRENGTH AND TEMPERATURE OF THE COLOR.
The tonal value of a painting. It is the dominant color. Each color has a pure tube tone and tonal value: yellow has a clear tone near white, red and orange have average values located in the middle of the tonal range, blue, green and violet have dark values. In a table is the ambience of a paint color.
lighten or darken a color:
Most white tend to cool colors to which they are mixed by reducing their intensity. As for the black, it tends to neutralize them by making them also lose their intensity. Only practice teaches us the exact proportions of a particular mixture.
INTENSITY OF COLOR: A
intensity can be strong (or strong), medium or low (or dull). Some colors have a wider range than others: The
cadmium red has more than twenty shades ranging from pure hue to its reddish gray, while the emerald is limited to eight or ten shades. A bright color can be a red fruit, average a few nuts, low, boxes or cans of white or neutral color, a tablecloth, a tin opener.
THE TEMPERATURE OF A COLOR. It
Chevreul (eighteenth century) that must be a methodical classification of colors by using a circle divided into 12 equal sections called color wheel.
In the color palette, there are cool colors and warm colors. If we place
cadmium red light at the top of the palette, warm colors are right in the direction of clockwise. Permanent green light is low, the opposite of cadmium red light.
Warm colors (examples):
Cadmium Red Light (primary), Orange Cadmium (secondary), burnt sienna, cadmium yellow medium, natural sienna, cadmium yellow light (primary), yellow ocher, yellow Cadmium pale Green English Green bladder Permanent green light (secondary).
Cyanotype (examples):
Veronese Green, cerulean blue, phthalocyanine blue, cobalt blue (primary), Ultramarine Blue, Cobalt Violet Red (secondary), Garance, brown alizarin, alizarin crimson, burnt umber.
You can either according to his tastes, to complement its range, depending on subject to translate, add the following colors: Red
vermilion, Naples yellow, yellow Japanese lemon yellow Sahara Yellow March tan flesh, Japanese green light, emerald green, blue hydrangea, blue touareg, violet Egypt Van Dyck brown, ivory black, titanium white ...
ocher yellow, burnt sienna, natural umber burnt can be obtained by mixing, but because we confine often used, it is preferable to add.
CHANGING THE TEMPERATURE OF A COLOR.
Comments:
-To determine the temperature a color, it is to compare it to another. Indeed, a color is at its maximum intensity when placed next to its complement.
Avoid placing side by side two primary or two secondary schools in the same intensity, intensity nullified.
For an object or subject of any kind, informed, the color temperature must be consistent with the source.
Example: an apple, a pear or a white sheet illuminated by a yellow light, all plans informed of these objects will contain a little yellow.
In the shade, it will be necessary using a bit of additional temperature of light.
Example: apple, pear or the water will contain a hint of purple, yellow complementary color.
In the case of using a lighter color when it is illuminated by light of similar hue, it becomes dull lit by a complementary color.
Example: the illuminated part of the apple red and yellow is more intense under the warm light and shadow will be a lower intensity and vice versa. The intensity will be less strong and the parties informed the shadow will shine more.
GRAY ECLAT:
Mix complementary
Example: An tendency bluish red as carmine or crimson alizarin mixed with a rather cold green as emerald give a dark color around the black. Suffice it to degrade the color obtained with white to get the cutest gray varied. The mixture
burnt sienna and ultramarine can make the gray rocks and wood exposed to weather for example.
SHADOW AND LIGHT:
To create an atmosphere and set the distance between two objects or subjects. To unify a complex and revealing the strength of a shape. Their effects lend character to a table and allow us to place a time, season, location.
The light and shadow to give shape elusive subjects such as water, reveal the rough or smooth surface and especially allow the unification of the table.
