A As ceramic tiles are made of natural materials that are compressed under high pressure before being kiln-fired at high temperatures, some shade variations will occur. Tiles will have variations in colour tones within the same batch, and more so from batch to batch. For some tiles, these variations are part of the design to give the tiles a natural characteristic and charm. In order to ensure the shades are harmonious, before installation we recommend to dry lay and check the effect under lighting condition which is as close as possible to the final lighting condition, so that the final effect is as desired.
