The holidays bring the NXT community a nice little gift on the LEGO Shop@Home site - the Hi-Technic Color Sensor.

See a rainbow of color!

Using the NXT Brick (sold separately), the Color Sensor enables your robot to distinguish not only between black and white, but also a range of bright and pastel colors.

Does not include connector cable.
This is the individual component, and does not include the NXT Intelligent Brick, software or any accessories. It requires the complete LEGO® MINDSTORMS® NXT set (#8527) for use.
