Method 1:

Put the color sensor on the white object, turn on the red filter, at this time the sensor will emit the frequency, count the emitted frequency, when the count reaches 255, there is a time, this time is recorded as T1.

Turn on the green filter, at this time the sensor will emit different frequencies, count the frequencies, when the count reaches 255, there is another time, and this time is recorded as T2.

Turn on the blue filter, at this time the sensor will emit another different frequency, count the frequency, when the count reaches 255, there is a third time, this time is recorded as T3.

Then put the sensor on the object to be measured, turn on the red filter, count the number of counts in T1 time, and record this number as N1.

Turn on the green filter, count the number of counts in T2 time, and record this number as N2.

Turn on the blue filter, count the number of counts in T3 time, and record this number as N3

N1N2N3 makes up the three primary colors of the object to be measured.

Method 2:

Put the color sensor on the white object, set the timer to a certain time, turn on the red filter, at this time the sensor will emit the frequency, count the emitted frequency, and record this number as n1.

Turn on the green filter, the sensor will emit different frequencies, count the frequencies, and mark this number as n2.

Turn on the blue filter, and the sensor will emit a different frequency, count the frequency, and write this number as n3. Multiply by 255/n1, 255/n2, 255/n3 respectively.

Then put the sensor on the object to be measured, set the timer to the same time, turn on the red filter, then the sensor will send out the frequency, count the frequency of the emitted, and record this number as X1.

Turn on the green filter, and the sensor will emit different frequencies, count the frequencies, and write this number as X2.

Turn on the blue filter, and the sensor will emit a different frequency, count the frequency, and write this number as X3. Multiply by 255/n1, 255/n2, 255/n3 respectively.

The three primary colors of the object to be measured are 255*X1/n1, 255*X2/n2, and 255*X3/n3.
