The lighting design uses color light to cooperate with the performance to create a stage atmosphere, which is a complicated artistic creation process. This process reflects the designer's artistic accomplishment and technical experience. Different content and form of performances have different lighting designs, and there are almost no fixed methods and skills. Below we will introduce several methods and techniques for using stage color light in stage lighting technology.
　　 One, the use of the same shade
　　 The same color light refers to a group of colors that are basically similar in hue, but differ in density. For example, blue has medium blue, green blue, bright blue, light blue, sky blue, etc.; pink has orange pink, brilliant pink, pink, light pink and so on. The lighting design uses the same color lights to create a lighting atmosphere, mainly using their differences in brightness and color perception to form light and dark levels on the stage. If the stage is decorated with bright pink light, and the side of the entrance door uses pink light, the lighting effect formed in this way is based on the pink tone, with a certain difference between light and dark.
　　Furthermore, we can use the same color light to highlight the local performance area. In the performance area with mid-blue light, use light blue to project the local performance area with the side lights on both sides of the station. The difference in brightness makes the local area stand out. According to different needs, other "blue" can also be used, such as bright blue light, sky blue light, etc. For the lighting, you can choose backlighting, overpass lights on both sides, overhead lights at the proscenium, etc. according to the scheduling of the characters and the status of the set. The changes of parts can get different light and shadow effects.
　　 2. The use of contrasting shades
　　 Contrast color light refers to the contrast between cool color light and warm color light. In use, cool light and warm light are respectively projected on the characters or scenery in the performance area from different directions. Due to the contrast and contrast of the color light, a relatively strong color light effect can be obtained. In addition to highlighting the atmosphere, it can also enhance the three-dimensional sense of characters or scenery. When using contrasting color light, you must master the choice of different parts, such as front light and top projection light, front light and top backlight, and opposite projection of flowing light on both sides. Use the side light parts of the flyovers on both sides to project the performance area symmetrically with red and green lights. According to the required light and shadow effect, if the requirement is strong, the light can be medium blue light, if the requirement is more subtle, the light can be sky blue or light blue light. This method of lighting and color can be exchanged for a variety of shades, such as red and medium blue, orange and yellow and medium blue, pink and medium green and other contrasting shades. At the same time, it is necessary to grasp the relationship between the color, brightness and contrast color of the front light. If the front light and the top backlight use contrasting light, the sky blue light is used on the front of the stage, and the pink light is used for the backlight.
　　 In this way, in the refreshing blue tone, the character's body is studded with bright pink light. When using this method of lighting and color, the backlight has enough brightness to get the color effect of the backlight. When using the canopy, you should pay attention to the difference between the color of the backlight and the color of the canopy. If you use a dark bottom screen, pay attention to the direction and angle of the backlight beam, so as not to affect the harmony of the stage screen.
　　 Three, the use of single color light
　　Single color light means that only one color light is used in the performance area to form the lighting atmosphere required for the performance. According to the requirements of the creation, you can choose to use either cool light or
　　 can choose warm color light. The biggest feature of using a single color light is that the light color is relatively bright, and the color light will not dilute or change with each other. In the performance scheduling of drama and dance, sometimes a single color light is used to highlight a group of shapes that need to be expressed. For example, in theatrical performances, mid-blue light or light green light is often used to express night or dawn.
　　 In a dance performance, a single color light is often used to set off the strong lighting atmosphere of the group dance, and the mood and rhythm of the dance are constantly changing to enhance the performance atmosphere of the stage. When a single color light is used, light and dark are generally not emphasized. If a slight difference between light and dark is required, various methods can be adopted, such as lighting on one side and less on the other side; if the lamps on both sides are the same, it can be on the other side. Add yarn; you can also use the control system to slightly darken the luminosity on the side.
　　 Fourth, the application of similar shades
　　 Same color light refers to the same cold color light or the same warm color light. Frequently used cold colors include medium blue, green blue, bright blue, brilliant blue, sky blue, light sky blue, dark green, medium green, light green, brilliant green, purple, light purple, green lotus, etc.; warm colors include red and red , Brilliant rose, deep pink, brilliant pink, deep orange, orange, golden orange, golden amber, light coincidence, golden, medium golden, etc. Taking the medium blue in the cold light as the basic color light, and using the medium green light on the side of the end gate, it can form the feeling of the moonlight at night. If you need to increase the brightness of the front, you can change the front light to sky blue or lighter medium blue. If the light amber in the warm color light is used as the basic color light, and the red light is used on the side of the field gate, a more prosperous atmosphere can be formed.
　　 When using color light to create an atmosphere, it is necessary to grasp the relationship between the light and shadow effect of the color light and the position of the lamp and the brightness of the color light. The whole stage is covered with orange-red light, and a medium golden backlight is projected to the front part of the stage in the later part of the stage. In this way, the golden-yellow backlight of the characters in the performance area is very vivid. If the parts of these two colors are interchanged, the back light and shadow of the orange-red light on the character will appear dim. Only by increasing the lamp and the intensity of the strong orange-red light can a more vivid back light and shadow be obtained.
