Display color hue with 'displaySensorValues' command


Hi, I simply would like to use the robot brain as RGB color detector (displaying color hue value at the display and converting this into RGB color code). Therefore I connected the color sensor and used the ‘displaySensorValue’ command in a repeat-forever loop. When running the program two values are displayed on the screen. I guess the first one is the color hue value. But I do not have any idea what the second value is about.

Could you help me with this?
I would like to use this for students and need to know the answer befor they ask…

Many thanks!
