The stoplight-inspired system is universal and thus makes the most sense as a social distancing indicator. However, as the concept gained momentum, many found that the colors of the bands didn’t matter as much as the custom design on the wristbands. So as long as the wristbands were imprinted, debossed, or embossed with their social distance preferences, the silicone bracelet colors were not as important.
This was especially popular for couples getting married; they would often match the bands to their wedding scheme, and guests would keep their bracelets as a sentimental wedding favor. This was perfect because not only was everyone staying safe, but they didn’t have to wear a red, yellow, or green bracelet to throw off the color of the wedding. Furthermore, you could include the couple's names or initials along with the wedding date to make the bands even more personal and special.
Educational institutions also opted to go this route by selecting bands that coincide with their school or university colors. This way, students, staff, and visitors alike could express their school spirit while still feeling safe. Red, yellow, and green social distancing bracelets would throw off the school spirit if those colors were not their school colors and people had to wear them to school events.
