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!
