What is the lucky color in Hong Kong?

Can you tell me, what is considered the lucky color in Hong Kong and why is it held in such high regard? Is there a particular cultural or traditional significance tied to this color, or is it more of a modern-day superstition? How does this lucky color influence the choices made by the residents of Hong Kong, whether in fashion, decor, or other aspects of daily life? I'm intrigued to learn more about this fascinating aspect of Hong Kong's culture and traditions.
