Good color / light / photo sensors for line following?

Any recommendations for good sensors for line following / alignment? I’ve been looking around, but it’s hard to find much that doesn’t require being extremely close to the ground. Would some kind of a CV solution / camera looking at the ground be better?

There’s already a thread on this topic: Lining up with tape on ground for new game?

Specifically, the rockwell IR sensors have a long enough range for detecting the lines on the ground from any practical distance
