Pictorial arts: This is the phrase used to express the decoration of the dwelling, as they are two-dimensional surfaces with lines and colors that summarize a specific idea and colored photography, whether it is oil or tempera, or gouache and water colors, or frescoes, or fixing with heat, duoku, casein, or any other It is one of the other modern materials, as it falls within the scope of graphic arts, but drawing is the most fresh means of expression and an indication of the artist’s idea, and it also falls within this scope. And the drawing may be produced by means of a pen or feather and ink or by paint and colored pen, and by pastel or by Charcoal, either (engraving), which is one of the printing arts resulting from printing processes ... It is also part of the graphic arts, and it can be produced in three ways, etching with acids on metals such as zinc and copper, etching without acid on linoleum wood, zinc and silk screen 000 or etching using a chemical method On the level surface of the stone in the (lithograph) ... Also, photography, whether it is black and white or color - static or moving - is part of the graphic arts, as is the case with mosaics or mosaics, where architectural surfaces or separate paintings are decorated with squares of stones and glass Colored • Forms of graphic arts: When analyzing the graphic arts to their original forms, we find that they fall into three specific groups: wall shapes, paintings, and newspapers. Wall shapes are surfaces related to architecture, and although most of the major murals were of frescoes or hot-fixed colors... it happened in the Renaissance and modern times that large-scale fabrics were attached to the walls, the painting of which was a colored drawing executed on the easel and then fixed in place On the wall • Problems of the graphic arts: The basic problems of the graphic arts of designing the surface, space, shape or movement using line and color (in its degrees of light and dark) and linear atmospheric perspective. With the line, the artist can create the deception of space or shape for mass or movement, and the direction of the line and its own distinctive personality helps in that. The oblique line may be more effective than the horizontal line. The shifting lines give rise to a perception of breadth called linear perspective, and the overlapping lines give rise to a formal deception, and the state of the line determines certain characteristics. With color and its degrees (or lightnesses and darks), the artist can take into account the local color of a real subject or the differences of types and intensity, and he may completely ignore the real color and create, for example, threads of green or purple color, as we see in the works of the artist who made the decorated canvas. And with the harmonious linking or the great contrast of colors with the lines, the artist can make the illusion of space, which is called the aerial perspective, and the illusion of shapes, which is called shading. The color has an emotional impact more clearly than the line. Also, some colors, such as red, have a strong effect - and by changing the color contrast or intensity, the situation of the photographer may change as a whole, as seen, for example, in Picasso's dark painting, which he called "the blue age, and strengthened by sharp lines," and in his more optimistic painting, "The Age." pink blue”, and finally in the happy painting “The Pink Age”. Thus, the strong contrast and elusive crossing between light and dark can define the situation in the graphic arts of Bayeux
