Thank you Bill & Zack for your help! I have a b/w copy of the rules and I just assumed it should have had orange accents like the other sensors. I should have done more through research (like I tell my team..) I ordered the sensor and should be all good now!
Kind regards,

> Technically, the optical sensor which comes with the current educational kit is the "light sensor" which can detect differences in ambient and reflected light (using its red LED). When used to detect reflected light, the light sensor can detect differences in both black and white and different colors, but it can only determine the intensity of the reflected light (almost like "grey scale"). This sensor is essentially color-blind and its purpose does not include the ability to distinguish between different colors (e.g. blue vs. red). The light sensor can be calibrated to adjust to the light levels expected during the sensor's operation.

> The color sensor is available either by separate purchase (using the link you cited) or when you purchase the Version 2.0 "retail kit". The color sensor can distinguish between different colors of light (distinguishing among six colors) in addition to what the light sensor can detect. Also, if desired, it can be used as a color lamp, emitting red, green, or blue light. Assuming you are using NXT-G to program your robot, your team would need to use the latest version of the software (LEGO® MINDSTORMS® Education NXT Software 2.1). The color sensor cannot be currently calibrated. For a little sensor trivia, the although the color sensor appears to have three devices on its front end, only two of the three are actually used. The third is just a feature to look pretty.
