<p>As I know there is no way to turn on green/blue reflected light on EV3 color sensor.</p>

<p>Is there a way to do it using NXT color sensor and EV3 controller?</p>

(Asked by: username_0 on 2015-08-23)

As I know there is no way to turn on green/blue reflected light on EV3 color sensor.

Is there a way to do it using NXT color sensor and EV3 controller?

Or the only way is to use NXT controller together with NXT color sensor?
