Trademark design, brand image.

1. Trademark design: The trademark design of a listed company needs to be unique and recognisable. However, green is too common and lacks uniqueness, which is not conducive to the recognition and memory of the trademark.

2. Brand image: The brand image of a listed company needs to be consistent with the company's image, product features and other factors, and green cannot accurately convey the company's brand image and product features.
