As you change color, you can observe the spectrometer close to your smartphone
You can observe the spectrum.

For example, in the case of yellow, the spectrum of red and green is visible
The reason is that the yellow color is a combination of red and green light (only red and green pixels are on to make it look yellow on the screen).

Also, if you make a yellow color by superimposing red and green quickly
It seems that there is a lot of difference between the actual yellow and the eyes.

However, when we compare it with a spectrometer, we can see that the color is slightly darkened and the same spectrum appears. This means that it is a little yellow, but it is yellow.

Made for easy observation.
