Color Detection - How far away?

If I wanted the robot to detect certain colors like Red,Blue,Green, how far away would it be able to detect. Does it have to scan it and be almost touching it, or can it recognizer say a sheet of red construction paper laying on the floor in front of it, or someone sitting in front of it with a red shirt on. Same for blue and green, etc. Would I have to build a linear actuator to reach out and almost touch the item to do this?

    The CMUcam can detect (and track) color blobs at a distance of several feet. How well depends on the size of the blob (in degrees of view) and on the lighting. Have a look at the documentation on Parallax's webstore page.

    Will do, I think this will work nicely for what I have in mind. Thank You, Mike.
