It consists of three principles of induction of primary colors, if you know the composition of all types of color values, you can know the color of the test object.
For TCS230, a color filter is chosen, only a certain primary pass is allowed, it is stopped by another color.
For example, when choosing a red filter, the incident light can only be stopped in red, blue and green, so you can get the intensity of the red beam of light.
For the same reason, the choice of other filters, can obtain the intensity of blue light and green light.
Through these three values, the color of the light can be projected onto a TCS230 sensor.
