In the production room of Kwantz, a row of Kwantz concrete slabs is on display. Some radiate a deep green glow, others reveal warm red hues. Under the critical eye of the team, each one is evaluated—not only for colour, but also for its resistance to coffee, oil, and water. The result of this meticulous work? The brand-new Astor colour range—a collection that blends colour intensity with functionality, like only Kwantz can.
