Javadoc error - ColorSensor interface

[AlecHub]

Javadoc says the argb() method of the ColorSensor interface returns "hue", which is incorrect.

argb() returns Alpha/Red/Green/Blue channels packed into an int.

You have to use the colorToHSV() method to convert the argb() value to HSV:

float[] hsvValues = new float[3];
Color.colorToHSV(color_sensor.argb(), hsvValues);
float hue = hsvValues[0];  // [0, 360]
float sat = hsvValues[1];  // [0, 1]
float val = hsvValues[2];  // [0, 1]
