<p>The decorative wall tiles are easy for the non-specialist to assemble into patterns, and are in the shape of an isosceles right-angled triangle and are all of the same size. The tiles are in different colours with some being all black and others ranging from partly black and partly red to tiles which are all red. Another range of tiles varies in a similar way between all red, red and white and all white. Yet other ranges combine black and blue and blue and white. These tiles can then be combined to make patterns of varying colour brightness, shade, and colour saturation.</p> |
