Chromatic circle

Abstract: The pictorial medium of representation uses shape and color to serve two basic functions. One of them connects things belonging together and separates the ones that should be apart. The second function serves identification. Using shape and color, it distinguishes kinds of people, different professions, and even individuals. Soldiers or policemen are recognized by what they wear; black and white distinguish the mourners from the happy brides, and the images of the Madonna are known by her blue coat and red dress. In a confusingly complex world, color distinguishes objects from their setting in the environment. A fire hydrant stands out in the street, and the distinctively colored buttons or handles of a machine guide the eyes to direct action. So do the colors of traffic signals. The pictorial use of shape and color is based on the nature of their elements. Shapes derive from line, circle, disk, or square; color derives from the three chromatic primaries, red, blue, yellow, and the achromatic black and white. Each of the three secondary colors-orange, green, violet-holds the balance between two primaries of equal strength. Each of the six tertiaries stands between a primary and a secondary. Each therefore unites components of unequal strength. Together, the three categories form the chromatic color circle (fig. 1). The three categories of color have different characters. The primaries are the basic pillars of color composition. They are powerful and inflexible and therefore hard. Their presence influences their neighbors, but they are not influenced by them. The secondaries are also balanced, and each of the primaries of which they are made up connects with its neighbor outside. Therefore the secondaries serve as bridges. The dynamic influence of a secondary can pull to the left or the right, depending on the attractive power of the neighbors. When, for example, a green secondary is pulled by a strong blue on the left, the "traffic" on the bridge moves in that direction. Black and white, the fourth and fifth primaries, lie outside the chromatic circle. Therefore, all color systems are three-dimensional, spheres or cones, with the central axis formed by the scale from white to black. The differences between the three categories of color account for what is called the difference between cold and warm colors. The sensations of temperature are paralleled by qualities of color.' The straight inflexibility of primaries makes them feel cold; the complexity of secondaries and tertiaries gives them a flexibility that makes them akin to warmth.2 The expression of colors is influenced also by their association with phenomena of nature. White and yellow look like light, green like foliage, and red and pink have the warmth of blood. Black looks like the darkness of night. Therefore when a modern painter changes natural colors, his colors look like deviations from the natural ones. When Emil Nolde makes a face green, it assumes a deadly paleness, and the red water of the ocean looks warm. I mentioned that primary colors influence others, but are not influenced by them. It is also true, however, that by appearing in the company of others they can form a partial or complete whole. The three primaries become a whole by complementing each other because they comprise all the chromatic elements. Two secondaries will do the same; for example, in orange and a violet overlap and cover the chromatic whole with a surplus. But it would take all six tertiaries to make up a whole.

Abstract: The invention provides paint capable of shielding a chromatic circle inductor and a process for coating the chromatic circle inductor. The paint capable of shielding the chromatic circle inductor is characterized by comprising the following materials in percentage by mass: 25-50% of chromatic circle inductor paint, 20-55% of soft magnetic ferrite magnetic powder, 10-30% of liquid curing agent and 10-30% of diluent; the manufacturing method for the paint capable of shielding the chromatic circle inductor and the process for coating the chromatic circle inductor comprise the steps of coating for two times by using the paint capable of shielding chromatic circle inductor, and then coating for two times by using the paint capable of shielding chromatic circle inductor. The paint capable of shielding the chromatic circle inductor and the process for coating the chromatic circle inductor have the advantages that interference on other parts caused by leakage flux generated in operating of the chromatic circle inductor can be effectively shielded; the cost of the coating can be greatly reduced; the inductance value can be increased; the self-resonance frequency is increased; and the paint is mainly suitable for packaging of the chromatic circle inductor.

Abstract: The utility model relates to a chromatic circle resistivity quick-checking card, which is marked with color identifying symbols on a resistor. The utility model is characterized in that the quick-checking card is composed of two sides, wherein, one side is used for checking the resistance of five-color circles; the other side is used for checking the resistance of four-color circles two sides are separately provided with chromatic circle holes and the numerical holes of corresponding chromatic circles; the middle is provided with five circular rotating plates which are arranged by turns and are corresponding to the resistance values of chromatic circles. One side of the five rotating plates is matched with the five-color circle side; the other side is matched with the four-color circle side. The five rotating plates are respectively arranged corresponding to circumference according to international universal colors and values. When used, the chromatic circles are aligned to the color holes; the value hole at the lower end displays the numerical value and the allowable error value of the resistor.
