There are two ways to put color into a surface material. One is superficial. One is permanent. The difference matters more than most people realize.
The superficial way.
Ceramic tiles are colored with glaze — a liquid glass coating fired onto the surface of the tile. Paint is applied on top of whatever is underneath. Powder coating sits on the exterior of a metal surface. All of these methods produce color that lives at the surface level only.
They look perfect when new. The problem is time. Glaze chips. Paint scratches. The color lifts, and what’s underneath is almost always grey, white, or the base material — which looks nothing like what you specified.
The integral way.
In UHPC, color is introduced as oxide pigment at the mixing stage — before anything is cast. The pigment becomes part of the concrete matrix itself. It disperses through the entire depth of the material.
There is no separate color layer. There is no surface that can be scratched away to reveal something different underneath. The color you see on the surface is the same color throughout the full thickness of the piece.
What this means in practice.
A Mix Matter sink in terracotta is terracotta all the way through. A tile in forest green is forest green from face to back. Daily use, cleaning, minor impacts — none of these change what you see. The color is structural, not decorative.
For designers specifying surfaces in bathrooms, kitchens, or any high-contact environment, this distinction is fundamental. You’re not choosing a finish. You’re choosing a material.
The palette.
Mix Matter offers 62 pigment colors — from the lightest ivory and sand through mustards, terracottas, sage greens, cobalts, and graphites to near-black. Every color is available across every product in the collection.
Because pigment is mixed by weight and ratio, colors are consistent across batches. A project that orders 200 tiles in cobalt and then needs 50 more six months later will get the same cobalt.
The honest caveat.
Screens cannot fully represent concrete pigment. A monitor shows light — concrete absorbs it. The same color looks different on a phone screen, a calibrated studio monitor, and in a north-facing bathroom at noon. Order a sample before you specify. Always.
