Traffic infrastructure products serve as a reminder for people to comply with traffic rules and have a significant impact on families. They also offer a variety of color combinations for their use, thus influencing their appearance.

Warning colors, such as fluorescent yellow-green, are used for general signage, warning signs, and the shapes of traffic signs for pedestrians and children. Orange or fluorescent orange is utilized for warnings and directional signs in road operation areas. Text, graphic symbols, and some symbols are presented against a black background. Blue signifies instructions and compliance. Red denotes prohibition, stop, or danger. Regardless of the weather conditions, people can understand and see these colors. It is only then that they can fully fulfill their role.
