This turn of phrase with its example has served to define the first dimension, which is precisely the line. Obtained the line, we live with another line (as we did for the point) to the distance we want. Moving a line to another line generates the surface and then the second dimension. The solid, representing the third dimension is given by the tension of a surface with another surface. Let's recap quickly: two points in the line voltage generated, two lines are the live piano, live two surfaces give rise to the third dimension. What has not been said before deliberately not to put too many irons in the fire, is that the line through multiple points results in an effect called surface perimeter. In this case, the line passing through the most points is called a linear medium. This definition does not indicate a surface but the feeling of the surface, as it is in fact a perimeter vacuum. Even in this case the characteristic of the linear medium is given by the measure. The linear passive rather is the condition of the surface and the line is fully sustained. The characteristic of linear passive (surface) is primarily weight (light or dark) second quality (color) and third measurement. Any operation or pictorial graphics to show itself uses this alphabet that enables mastery of the vast language with which art is expressed.
The color is not only the fluid paste that we use to paint our room. As harmless, the photon bombardment to which we are subjected every day, involves physical and mental reactions not of secondary importance. It will not be forgotten that the definition of a primary color was green put in the place of the yellow. The hard color to twelve parts with which you are familiar with the school, the green is a secondary color, and here was designated as primary. And 'well protected from being unequivocal, saying that to put the yellow instead of green is a practical agreement, since, for mixing colors (subtractive synthesis) may not get the yellow. Since in reality prevails due to the use of subtractive mixture of pigments, it explained why it is more convenient to reverse these colors. Additive synthesis (mixture of light projected) is less common, even if it matches the correct definition of primary generators. If all the colors in addition give white, subtraction (mixture of pigments) produces black. The colors, unlike the musical chords, when mixed together can not be separated and take on a character. If the primary colors with which they are often painted children's toys have their maximum loudness of saturation, is about the position they occupy on the hard color. More colors are made up and have less character. The colors is our visual alphabet and in many cases replaces the word. All colors except gray have their complementary color that is opposite to what we are looking at. The black to white, green to red, blue to orange, violet to yellow and gradually all the others. The gray, which will be discussed later, poses to the human eye is a condition which is of particular importance to the stability of the retina. What does this mean in terms of additional visual process? It means that if the eye sees color and sends stimuli to the brain to rebuild it, the brain is able to simultaneously produce the opposite of the color observed. To view the complement of a color is hard enough to fix the color and then close your eyes. For a few seconds will be printed in the brain of the opposite color observed. It is the same if instead of closing their eyes direct their gaze on a gray screen. Font color. The colors of objects in everyday life are obtained by subtractive. It means that you need to get mixed together. From their mixture produces a color that will have its own character, weight and color of a character tono.Per means its placement on the hard color. The colors that make up the central triangle, said just the primary paint: red, blue and yellow, are more commercial character of the circular disk placed in the shade. To weight or tone of a color we mean the ability to lighten or darken a color by using white, black and gray. It 'can get a different tone even mixing different colors of two different brightness level. The tone is ultimately to indicate the degree of darkness of a color or clarity. The physics considers the color from the viewpoint of electromagnetic vibrations as we have seen that generate the sensation of color. The chemistry is concerned with the molecular composition of the pigments and their color fastness. Physiology perspective, as a fundamental field of investigation of the relationship eye - brain, is given the task of investigating the relationship between function and anatomical parts of the eye of light. Psychology deals with the effect that light waves have on the psyche in terms of mental and physical response. It 'a matter of psychology, through the symbolism of color, define the subjective limitations to which each individual is responsible.
