3CM PIETRA Ombra

3CM PIETRA Ombra originates from a contemporary reinterpretation of Portuguese limestone, transformed into a high-thickness sintered stone slab designed for drive-over outdoor paving.
The surface expresses a warm and natural chromatic balance, where the dominant colour develops through soft, enveloping tones that make outdoor spaces welcoming while maintaining a rigorous architectural language.
The colour palette ranges between warm greys, mineral beiges and subtle pinkish nuances, with tone-on-tone transitions that keep the overall look compact and harmonious. The colour is never uniform: micro-variations, soft veiling and fine speckled details cross the slab discreetly, creating visual depth and a controlled natural effect.
The graphic pattern recalls the authentic materiality of limestone, with a soft, velvety visual texture, free from aggressive contrasts. The surface conveys a sense of balance and naturalness, enhancing light and interacting with other materials without overpowering them.
