Vietnamese TV Host Trấn Thành Discloses Long‑standing Color Blindness on Running Man Vietnam

Trấn Thành, a popular Vietnamese MC, revealed that he has been living with color blindness for 39 years. During the latest episode of Running Man Vietnam season 4, a challenge required contestants to select flags of specific colors, prompting Trấn Thành to admit he struggles to differentiate similar hues. Co‑host Ninh Dương Lan Ngọc offered to guide him to the correct flags, and his wife Hari Won has previously helped him on other programs.

Trấn Thành has spoken about his condition on several occasions, noting he can identify basic colors like red but often cannot tell apart subtle shades or mixed tones. The disclosure sparked amusement among fellow cast members and viewers, highlighting the practical challenges the condition poses in televised games and dress‑code situations.

The episode underscored how the host relies on teammates for visual cues, turning his personal limitation into a light‑hearted moment on the show.
