how do you get two different colours of green on a football field?

Answer 1

In addition to mowing the grass in different directions, you also use a roller to make the grass bend in opposite directions.

"Whatever pattern you make is revealed by the light shining off of the bent grass. A checkerboard design is created by passing over the grass in side-by-side rows, first going north to south, then making east-to-west stripes in the grass that intersect the north-south stripes. In this way, you alternate the way the grass bends. When you look at your lawn, the stripes of grass leaning away from you will look lighter. This lighter green is caused by the sunlight reflecting off the entire blade of grass. In the darker green stripes, formed by the blades of grass leaning toward you, the sunlight is reflecting only off the tips of the blades."
