1. Environmental variation
Color IS light. The color that you “perceive” consists of both the surface of the tile, and the reflection off the tile of its environment (lighting, furniture, large fixtures, cabinets, wall color or furniture). This is why it is so important for the customer to either see the tile in their environment or for them to understand that their tile will look different than it did in your showroom. If they paint their wall dark blue, their tile will look different. If they have incandescent or natural light, the tile will look different than under those cool blue fluorescents in your showroom.
2. Variation from shade to shade (die-lot)
This is the toughest shade variation to anticipate. This variation is the “die-lot” or “shade” variation is inherent in producing a “unique” product. The best way to handle this type of variation is to keep a range of “acceptable” shades of tile in a bin. As each new shipment is received, the new tile is compared against these “key” tiles. If it is distinctly similar, the tile goes into stock. If new colors have been added or deleted or if the tile is questionable at all – it goes to the sales manager for approval. If the difference is significant – the sales manager should have all showroom samples changed out, including all customer samples on display.
3. Variation from tile to tile
“Ceramic tile bodies and glazes are created from elements of the earth – clay, water, sand, minerals. Just as these materials vary in the natural world, the end result of their combination will also produce variations in the surface color and texture of ceramic tile. These natural color variations and markings enhance the individuality of each tile and result in a sophisticated but understated design sensibility that characterizes each tile and is designed to provide maximum performance and classic good looks.”
