Two people, one in gray and one in white, sitting on a bench by a walking path looking over a field at a forest during autumn.
The person in the red and the person in green, are briskly walking by the bench on the pier, on a rainy winter day.
The two people cannot be both walking and sitting.  They are described as wearing different colors in the two sentences, red and green and gray and white.
