Stage lighting design time the use of color

Stage lighting design time color is the use of Theatre Arts is one of the important means in the use of color, to master his skills and rules.

Color addition and subtraction for

As long as the master of painting color, can use several colors from the color of the myriads of changes. Seasoning mix is the application of the color always used " for subtraction " rule. Understanding the law of superposition, the filter can be transferred to the various color. The stage lighting to different types of filter are superposed together, can be obtained through the light required for a variety of color. The stage lighting used the same painting palette of this " rule for subtraction ". But it is worth mentioning that the stage lighting should not only use this method, but also must use " color added " method to obtain a different color. The primary colors of light red, green, blue additive white regularity. If we put the " color. " " the law and rules for subtraction " confused, it is very difficult to find a reasonable use of color from the laws of science. In fact, color TV and color photographic color films also use these two rules. Red and green are mixed to produce a yellow light, and the color yellow is not possible from the red and green with it, and as the yellow light can produce mixed white garland. The colors red and cyan blue and green generating intermediate colors yellow. This is in fact the complementary color, also known as mutual as the remaining chromatic. That two kinds of color additive to produce white settlement, called the two other remaining chromatic light, it is white sum rule. Stage light filter stack " for subtraction " to obtain light and stage two different color lights are mixed together in the " color added " are two different color matching method, must make clear these two different rules, then on the stage lighting design practice, familiar with him, to get the required artistic effect.

Stage lighting luminous body and the filter application

Study on Application of stage lighting color skills, must be familiar with the use of tools -- stage light and color filter. Just as the artist painting on must be familiar with paint, canvas words pen and performance, the stage is more use tungsten lamp. As a result of tungsten in ensuring normal life can bear bear temperature, can only send 2800K color, color slants yellow, suitable for warm color filter, when expressed warm scene, such as the blue night is difficult. The light source is missing in the blue component, so through the filter after about a loss of seventy percent of the light, reduces the light illumination, his pure color master is poor since the tungsten halogen lamp was invented to make color temperature reached 3200K, which is almost limit, its color is still warm, if increase tungsten wire temperature will cause life is greatly reduced, there would be no use value.

Stage drama is a visual art, but the optic nerve is different from the color film or television, eye color cell weak, in light of different colors is wrong. Such as the human eye on a moonlit night of the dark is almost blind. The color of the distinctions than film sensitivity is much lower, stage lighting solutions to important problems, if not with the aid of a gas discharge lamp or a metal halide lamp development, improve the cool light brightness and purity is very difficult. Currently used by using the light lighting dimmer ( control the light changes) are not ideal, it was limited in the stage used a lot dimmer, due to the voltage drop caused by the light warming color ( the voltage of each lower 1V color temperature reduces 10K ) special effects cold tone luminescent dimmer. How many years have been studied using adjustable light fluorescent lamp to solve this problem. In recent years, the film started using variable frequency adjustable optical fiber line three band fluorescent lamp. Now the stage lighting color filters used for fear of ester resin ( also known as polyester film) staining. The use of light, but it is very difficult to completely without legs color. Well-known manufacturers of color filter up to more than 100 kinds, often called it a series of filters, each filter between the differences are very small, because television is very sensitive to light, it is not the difference between the two, the naked eye can be found in TV color difference and color differences, it is almost in the film not acceptable. But for stage lighting, doesn't need to be so high. China Institute of fine arts stage lighting professional committee has organized the Beijing and Shanghai two light experts selected filter, select commonly used filter regularly more than 20 kinds of. Most experts advocate the use of color and the sum of the light for subtraction rule to obtain the desired rich color changes.

Because polyester resin filter is difficult to do not fade, so some performances retain repertoire of foreign theater remains using colored glass filter. The stained glass in the molten glass into some metal or its oxide and different colors, and the color will not fall. This will ensure that the repertoire performed at the time of mass does not change.
