sensors.color1.onLightDetected(LightIntensityMode.Reflected, Light.Dark, function () {})
sensors.color1.pauseUntilLightDetected(LightIntensityMode.Reflected, Light.Dark)
sensors.color1.pauseUntilColorDetected(ColorSensorColor.Blue)
sensors.color1.color();
sensors.color1.light(LightIntensityMode.Ambient)
sensors.color(ColorSensorColor.Blue)
```

## Touch
