📜 Origin & History

The visual impression of Cement Gray first originated from late 19th-century construction sites. Freshly poured concrete, during its curing process, presents a semi-wet greenish-gray. This fleeting intermediate state was recorded by architects, becoming a color symbol of the construction process in the industrial age.

The Japanese Metabolist architects in the 1960s used Cement Gray as an experimental material color. Kiyonori Kikutake's Sky House displayed the structural logic of the building with exposed Cement Gray surfaces, transforming the sense of being unfinished into an avant-garde aesthetic statement.

The Brutalist architectural movement made Cement Gray one of the most controversial colors of the 20th century. Le Corbusier's Unité d'Habitation in Marseille challenged traditional architectural aesthetics with large areas of rough Cement Gray walls. Criticized as 'ugly' by detractors, it became a bible for a generation of architects.

Today, Cement Gray is experiencing a revival in interior design. The popularization of microcement finishing techniques allows Cement Gray to move from large public buildings into ordinary homes. This gray tone, retaining traces of construction, has become a core element of the minimalist lifestyle.
