Cement is a kind of gray. Gray is the simplest, so simple that the whole world is wrapped in it but doesn’t care; Gray is the most complex, so complex that all the colors on the palette can be mixed to get this chaotic beauty. Whether simple or complex, it is a kind of energy, which is pregnant with brand-new colors. For the product, this new color is psychology, imagination, comfort and Zen. The gray color of cement has no boundaries.
