Leaves textured in S-shape reduce the unnatural, plastic look of your synthetic lawn. While natural grass is green because it contains a molecule called chlorophyll, with an artificial grass it is important to create a proper angle for sunlight to reflect in a similar manner without creating a mirroring effect. The S-shape of the blade helps our grass to look more realistic even on a very sunny day. While flat blades reflect the entire spectrum of light, making the grass appear white, S-shape helps to diffuse reflectance, texture, and color.
