Where Harmony Fits Best
Harmony is particularly good at bridging the gap between traditional and contemporary.
In a modern kitchen, the slightly weathered edges introduce character against streamlined cabinetry, stone worktops and minimal hardware. In a more traditional property, the 10x20cm proportions feel familiar enough to sit naturally alongside shaker furniture, timber and painted walls.
The colour you choose can push the collection in a very different direction.
White keeps the look light and understated, allowing the rustic edging and subtle variation to provide the detail.
Violet introduces a more unusual, atmospheric note and works particularly well when paired with warm neutrals and natural timber.
Blue can create anything from a relaxed coastal feel to a deeper, more dramatic kitchen depending on the surrounding materials.
Green brings an earthy quality that works naturally alongside oak, walnut, stone and aged brass.
For grout, I'd generally stay relatively close to the tile colour. Because the edges already provide definition, an aggressively contrasting grout can make the installation feel much busier than intended. A complementary white, warm grey or similarly toned grout allows the rustic character to remain visible without turning every joint into a feature.
