I’m unclear how to the calibrateLight block works. How does it know the sensor is over the dark or light area? Does it sample several times a second and find the min and max reflection in a given time or until the program ends. Are the calibration values stored or do I run the procedure every time? Also, if there are two sensors do we calibrate them individually.

For reference, here is the impl: https://github.com/microsoft/pxt-ev3/blob/master/libs/color-sensor/color.ts#L333
It resets the sensor, then collects readings until it does not change anymore, compute min/max range and applies a threshold. It does not store the results yet but it’s an excellent suggestion.
2 sensors is not supported. You would have to write your own sequence. I guess when we store the data things would be easier as well.
