In an interview with the Japanese fashion magazine, NET ViVi, the girls were asked to pick a name for their group with Chaeyeon thinking of the name, "Traffic Lights Team". Yena also suggested for "CatDuckButterfly" as the name since their animal personalities are cat (Sakura), duck (Yena) and butterfly (Chaeyeon). 
The group's name, "Traffic Lights", is a reference to their hair color during the interview, with Chaeyeon's red, Sakura's yellow, and Yena's light blue.
