Wearing a green color in the Ocean can trigger Ratu Kidul

Description:
In Central Java, particularly along the southern coast near the Indian Ocean, there is an old belief that wearing green to the beach is dangerous. Locals believe that green is a sacred color to Ratu Kidul, Queen of the South Sea, or Nyi Roro Kidul. Legend has it that Ratu Kidul loves the color green, and by wearing it on her beach, you might catch her attention. According to the myth, she might think you are trying to compete with her or that you are not worthy of wearing her favorite color, which can lead to accidents such as drowning or sudden disappearances.

Irrational Reason:
Green is the favorite color of the Ratu Kidul, or the Queen of the South Coast, so when you wear green it will trigger her anger and make her pull you into the sea.

Rational Reason:
Green can blend in with the sea and its surroundings, making it difficult for lifeguards or others to see someone. That is why ancestors try to avoid someone use green in here to improve the safety.
