Why dark grout makes colours sing

We are called Grouted for a reason. Ask what makes these mosaics look the way they do and the answer is not the tiles: it is the dark lines between them.

The grout is the drawing

Lay two pastel tiles side by side with pale grout and they melt into each other. Put a dark line between them and suddenly each colour holds its shape: the pink is pinker, the sage is greener. The grout works like the lead in a stained glass window or the ink line in a comic. It is the outline that makes flat colour graphic.

The Victorians knew

Look closely at a Victorian tiled path and the joints are almost always dark: soot-toned mortar framing every tile. Partly practicality, partly the same visual instinct. A century of foot traffic later, the dark line is also why those floors still read crisply.

The honest bonus

Dark grout forgives real life. Tea rings, coffee drips and Sunday gravy leave no history on a charcoal line. These are pieces to use, not to guard, and the way they are made assumes exactly that. Browse the results, always outlined in dark, in the shop.
