1️⃣ Red can stimulate the visual system and improve people's concentration. On the sports field, the brighter the color of the track, the easier it is to attract the attention of the spectators and make the game more enjoyable. 2️⃣ Red is a positive color that can inspire fighting spirit and passion in athletes. In competition, athletes are influenced by color, and red can stimulate their sense of competition and help them better realize their potential. 3️⃣ Red also has a good ability to reflect light, which can make the runway more dazzling in sunlight. At the same time, the red track is still clearly visible at night or in low-light conditions, ensuring the safe conduct of the race. 4️⃣ Red also has good durability and abrasion resistance, which can maintain beauty and practicality during long-term use. In short, the reason for choosing red for plastic runways is mainly because red can stimulate vision, stimulate athletes' morale, improve the visibility and durability of the track and other factors. But there are also more and more blue runways on the market at the moment, which are more visually comfortable and appealing. Blue is a cool hue that is more muted and calming compared to red. During long periods of exercise, the red track may give the athlete a feeling of tension and fatigue, while the blue track can give a sense of relaxation and pleasure, which helps to improve the mental state and performance of the athlete. Regardless of the color, it should be designed according to the venue and the needs of the sport.
