One summer day in 1947, young Yves Klein was sitting by the sea in nice, France. He looked up at the blue sky above his head and said, "this blue sky is my first work of art!

Since then, international Klein Blue, a color with great artistic vitality, was born in the world. Today, this pure and suffocating color has been popular in the design and fashion circles for more than 60 years, opening a new "feeling space" and being praised as "pure blue", "ideal blue" and "trust blue".
