How the finder works

01
Lightness & hue
For each tile colour, lightness and hue are calculated. The lightness difference between tile and grout decides whether the grout looks calm or clear – the same logic as the recommendation chart in the Grout Colour Guide.
02
Style & light as filters
Your living style decides which option comes first (calm, clear or accent) and whether a warm grout is preferred. Your room light decides between a light and a dark grout for clear contrasts.
03
Three perspectives
Calm, clear, accent – three recommendations with a contrast value. Compare variants directly instead of seeing just one option.

Frequently asked questions about grout colour

Is this real AI?+
No – the finder uses a rule-based recommendation system based on interior design heuristics. The contrast values are based on the calculated lightness difference between tile and grout (CIELAB) plus hue, style and lighting logic, not an AI model. This makes the recommendations consistent and transparent.
Can I change the grout colour later?+
Yes – grout can be routed out and regrouted. It works but requires effort. Better to make the right decision from the start. Use this finder before you order.
Which grout colour is easiest to maintain?+
Dark grout colours like Charcoal are far more forgiving of stains and dirt than light ones. Ivory and sand-coloured grouts look beautifully fresh but need a grout sealer for lasting brightness.
Does tile size make a difference?+
Yes, a big one. With 10×10 cm tiles more grout is visible – the grout colour carries more weight. With 15×15 cm the grout recedes and tile colour dominates. Charcoal grout with 10×10 is much bolder than with 15×15.
Is there a "safe" grout colour that always works?+
Sand is one of the most universal grout colours – it works with almost all tile colours and in almost all room styles. Not the most exciting choice, but it never goes wrong. When in doubt: sand.
How does my recommendation get into the configurator?+
Below each recommendation there is a "Configure directly" button. It opens the COLB Cube configurator with material, tile size, tile colour and grout colour already pre-selected – you only need to confirm the Cube size.

How to find the right grout colour

Grout colour is one of the most important design decisions for a tile table – and consistently the most underestimated. While tile and colour are immediately visible, the grout quietly determines whether the surface looks graphic or seamlessly unified.

Three factors decide: first, the tile colour (calm, clear or accent – see the recommendation chart), second, the tile size (10×10 cm shows more grout than 15×15 cm), and third, the interior style (Japandi favours calm tones, Urban-Industrial loves contrast).

COLB uses exclusively mineral grout – waterproof, durable and available in 10 colours: from Ivory through Sand to Charcoal. All 10 colours are available for ceramic tile tables; six standard tones for wood tile cubes.

Beginner's rule of thumb: A grout that is only a touch lighter or darker than the tile looks calm; a clear lightness difference looks clear – Charcoal with light and mid-tone tiles, Ivory or Sand with dark tiles. For every COLB tile colour the recommendation chart shows which grout fits. Use the Grout Colour Finder above for three tailored recommendations with live preview.
