Available Colors / Finishes

• Coal Black – A rich, deep dark pitch-black finish with a bold, dramatic presence. Coal Black delivers a sleek, modern look that anchors the kitchen with confidence and pairs beautifully with contemporary cabinetry and metallic accents.

• Anthracite – A deep charcoal-black tone with subtle granite flecking that adds depth and texture. Anthracite offers the sophistication of black with a softer, more dimensional stone appearance.

• Cinder – A dark slate gray inspired by natural stone. Cinder strikes the perfect balance between black and gray, offering a refined, grounded neutral that complements both modern and transitional spaces.

• White – A crisp, clean white with a timeless appeal. Bright and versatile, this classic finish enhances light and contrast, making it an effortless choice for both kitchens and laundry rooms.

• Truffle – A soft, earthy taupe blending warm brown and gentle gray tones. Truffle brings subtle warmth and organic elegance, creating a refined neutral that pairs beautifully with natural materials and layered finishes.

• Café Brown – A warm, medium brown reminiscent of milk chocolate. Café Brown adds richness and comfort to the space, offering a welcoming, grounded look with understated sophistication.

• Soft White – A creamy, warm white designed to complement quartz and stone surfaces. Soft White delivers a gentle, inviting tone that feels refined and cohesive rather than stark. Blanco’s newest color has been an immediate success, answering the industry’s demand for a perfectly balanced, in-between tone.

• Volcano Gray – A rich mid-tone medium gray with warm undertones and a smooth, stone-inspired finish. Deeper than light gray but lighter than charcoal, Volcano Gray offers a substantial, modern look and pairs exceptionally well with stainless steel and dark metal appliances.

Featured Throughout the Entire Color Collection: All Blanco Silgranit sinks are finished with a sophisticated eggshell sheen, offering a matte appearance enhanced by a gentle, light-reflecting glow.
