Pruning direction: The professional football turf we usually see, whether artificial turf or natural turf, is two colors, and there are reasons for different pruning directions. Lawns trimmed in different directions cause light refraction, which makes people look like two colors visually.
Practicality: The main reason for laying two colors in professional football field is practicality. These two colors can reduce the athlete's visual fatigue, and also let the referee see more clearly whether the athlete is offside. If they look at it with a green eye for too long, they will easily have hallucinations.
Increase the ornamental value: Paving the football field into two colors can give people a sense of patchwork, but visually increase the ornamental value of the lawn, making people look more comfortable and the lawn more practical.
