No. the colours are just 3 different scenes. imagine that the colours are levels. I want to walk into a level without the camera following me into it. I want to walk into one level without knowing what's in the other side until I get there.
When actor reaches XXX (the right hand edge of your scene) change the position of the camera (move it right by the same amount as the width of your scene).
