Hi Kathy,
When you're using the color sensor, in whatever block you're using, select Color Sensor - Compare - Color.  Then you can choose what color you want, as opposed to a reflected or ambient light intensity.  I've tried to attach a picture so you can see this.  There are also a lot of tutorials in the software that might be worth checking out.

Good luck!
Sonya

Hello all,

I am very new to the EV3 system. I did not use the color sensor with the NXTG. Can anyone direct me to a tutorial on how to program the color sensor? I'm not clear how it's different from the light sensor. It seems there must be a way to tell it to "find blue" rather than a certain reflected light intensity.

Thanks so much!
Kathy Molina
