That's a nice fast line follower. Are you using Line Tracking Mode and occasionally switching to Object Tracking Mode to detect the colour patch?
Are you referring to video above? Yes, that is in Line Tracking mode. It is configured for 2 colors (Black and Pink) Black is for line, and when it sees existence of Pink, it switches to object tracking mode, makes decisions based on what it sees, turns, etc. moves along the line for short time and then switches to line tracking mode.
