Hello, thanks for the post. So far we have only tested the NXT 2.0 color sensor. I believe that the EV3 color sensor is a new protocol, and we haven't yet figured it out. Other projects (mindsensors, lejos, etc) may have decoded the new LEGO protocol so you might be able to look at their code (if it's open source) and figure out how to talk to the EV3 sensor.
I am going to try to decode all the EV3 sensors this summer and see if they can be supported with the current Bricktronics hardware.
