Why are Seoul’s pregnancy-priority seats pink?

In 2015, Seoul introduced a more visible pink design for pregnancy-priority seats on the subway. Earlier signs could be hidden by a seated passenger, so the new design helped keep the seat’s purpose clear even when it was occupied.

EARLY PREGNANCY IS OFTEN INVISIBLE

The city also noted that pregnancy is not always visible in its early stages, which can make it harder for someone to be offered a seat.

COLOR AS INFORMATION

The pink upholstery is more than decoration: it helps passengers recognize the seat’s purpose even when someone is sitting there.
