well, just to point you in the right direction,

Spoiler for not the most efficient algorithm, but one of the simplest:

if the camera picks up the color drive forwards, otherwise, turn.

I don't use LabView, and I'm not good a image processing, so I'll be of little help with that, but I'd be surprised if there wasn't some pre-written library with a function, or whatever LV calls it, that can tell you if a certain color appears in an image.
