Terracotta has come back into fashion in a big way, and porcelain has made it a far easier colour to commit to than the real clay tile ever was. You get the same warmth and texture, the same sun-baked, earthy character, without the sealing and ongoing maintenance that traditional terracotta demands.
It suits a country cottage kitchen beautifully, but it works just as well in a retro-styled space or a Mediterranean or Moroccan-inspired room looking for a bit of warmth, or incorporated alongside more traditional elements for something eclectic and culturally inspired that still feels distinctly British. Because it reads as such a natural, grounded colour, terracotta rarely needs much else around it to make an impact, a simple white wall or a plain worktop is often all it takes to let the tone do the talking.
