The magic of lighting makes the stage extremely gorgeous and charming!
Red, green, and blue are called the three primary colors. Mixing these three colors in different proportions can produce various colors. There are two basic methods of color mixing: additive color mixing and subtractive color mixing. The so-called additive color mixing is a method in which when different colors of light are mixed, they add their respective parts of the spectrum together to produce a new mixed color. Show the color relationship of additive color mixing of light. When the three primary color lights of red, green and blue are mixed in equal amounts, we get:
Red light + green light = yellow light green light + blue light = cyan light
Green light + red light = magenta light red light + green light + blue light = white light
If the three primary colors of light are mixed in unequal amounts, various intermediate colors can be obtained, for example:
more red light + less green light = orange light
More red light + less blue light = pink light
Subtractive color mixing is a method in which when different colors are mixed, they each selectively absorb their corresponding parts of the spectrum from the incident light to produce a composite color effect. If the addition of any two colored lights can produce white light, these two colored lights are called complementary colors (complementary colors). For example, yellow and blue are complementary colors, cyan and red are complementary colors, and magenta and green are complementary colors. Therefore, yellow, cyan, and magenta are called subtracted blue, subtracted red, and subtracted green respectively. That is to say, the three complementary colors are all formed by subtracting a corresponding primary color from white light. Therefore, yellow, cyan, and magenta can be called the three primary colors of subtractive color. When the three subtractive primary colors of yellow, magenta, and cyan overlap, black is produced. In the process of subtractive color method, the density changes of the three subtractive primary colors control the absorption ratio of red, green and blue respectively, thus obtaining various mixed colors, which can achieve the same effect as the additive color mixing method.
