In history, there wasn't just one emperor like Chai Rong who lost his ambition to hobbies.
For instance, Song Huizong Zhao Ji was so obsessed with calligraphy and painting that he created his own style, "Slender Gold Script," and could absolutely be considered a master artist in calligraphy and painting;
Another example is Ming Xizong Zhu Youschool, whose favorite pastime was woodworking. It's said that the wooden birds he carved and crafted could fly in the sky, even the court artisans were amazed.
These emperors, who neglected their official duties for their special hobbies, were often exceptionally skilled and specialized in their respective fields.
Just like the Poyun Qing Chai Kiln produced by the Zhou Shizong Chai Rong, even in modern times, with current technological levels and exquisite craftsmanship, it's impossible to perfectly replicate this color.
