The seven colors of the rainbow and the mystery of the three-phase red, yellow and blue colors

I can't find blue among the seven colors; I don't know how to decorate it. "Although I can't find blue in the song. Phase systems are accustomed to seeing these three colors, but have you ever wondered why these three colors are one of the seven colors of the rainbow?

Chosen? What did the other four characters do wrong?

The advantage of using different colors for separation is that the phase lines can be distinguished. Now, the question is, what is the need to recognize all the phases separately?

Of course, there is. For some reason, you want to change the FedEx sequence. Then you can quickly get it if it is a different color wire. If you're going to change the phase of the same color, you have to read Confucius. Even if there is a doubt whether the change has been made at all? Such as twins

The human brain is susceptible to these three colors, and our optic nerves can easily sense these three colors. The wavelengths of these three colors are approximate. So the scattering is even. So it is easy to catch the eye.

The wavelength of red light = 700 nm Wavelength of blue light = 400 nm Wavelength of yellow light = 550 ml And if you notice, yellow

Ala's wavelength is the average value of red and blue. So, the RYB connection would be perfect for scattering in this area. The letters will be easily seen.
