First of all, we will study the mixture of colored light and green light scientifically. Adjust the three disks so that only a part of red and green are displayed, and bright red occupies the vast majority. Continue to increase the proportion of emerald green, let the gyro rotate, and check every time the proportion changes. Because the ratio of red to green is different, you can see orange, orange, light yellow and green yellow slowly. Look at the mixture of green and blue, so that emeralds are mostly at the beginning. Slowly lift the dark blue, and the middle color will change from blue to cyan (Conklan), dark blue and so on.
Finally, when blue and red are mixed, you can see blue and purple, light purple and other colors. You can see a variety of colors by changing the proportion of three colors on the gyro at will. Mix red, green and blue in a certain proportion, and you can get gray white. The basic principle is that there are three kinds of artistic somatic cells that people use to experience color (according to experiments). Each light matches a light wavelength, and the light wavelength is gradually elongated from purple light to colored light. If you mix three colors in different proportions, your eyes will look like real light. It's actually deceiving people's eyes. In fact, light at that wavelength is not easy to enter the eyes at all. Only the eyes feel the same as that wavelength of light. When the gyro is running at high speed, it seems that this color enters the eyes at the same time because of the retention of visual effects. I don't know, I don't know, I don't know. No, there are only two colors, if you draw seven colors. Why does the seven-color gyro turn white when it rotates?
The opaque color is determined by the reflected color light, and each part of the seven-color gyro will reflect different color light. When rotating, due to the temporary scene of human eyes, the reflected colored light is mixed and turned into white. Why do seven colors turn white after rotation? ..... Because white is composed of seven colors of light, people's eyes will combine these seven colors of light when running at high speed. It turns white. Why does the color gyro look white after rotating ... Because the number of rotations of cold and warm colors exceeds the stay time of the eyes, the cold and warm colors will be seamlessly connected like buying a movie ticket. Because of seamless splicing, the visual effect will stir them into various colors, that is, white caused by cold and heat, so the color gyro turns white after rotating. Why do gyroscopes painted with seven colors turn white ... white light can be converted into seven colors, and seven colors reflect all seven colors of light.
So it is incorrect to say that white light consists of seven colors. Because the luminescence characteristics of different colors are different from those of reflection spectrometer, various colors will appear. When the seven-color wheel rotates rapidly, the spectrometers of seven colors reflect at the same place. These seven-color spectrometers can cover all visible spectra and appear white. Because white light is composed of seven colors, more or less. When an object digests and absorbs six colors and only reflects one of them, everyone sees that color. When the CD is painted with various colors in proportion, it runs at high speed, which is equivalent to showing a movie. In people's visual system, it is usually colored in light. Because the frequency of light is 50Hz, and the number of gyro revolutions is several thousand Hz, the frequency difference is very large, which leads to the illusion of eyes, so it is colored. On the contrary, sunlight or high-frequency light is close to the frequency of the gyro, so it is black and white.
