Shade Variations in Tile
The colors and shading of all tiles vary to some degree from piece to piece and from run to run. It is recommended that several tiles from the same production run be examined in order to determine color and shade variations.
V1: Uniform Appearance
Differences among pieces from the same production run are minimal.
V2: Slight Variation
Clearly distinguishable aifferences in texture and/or pattern within similar colors.
V3: Moderate Variation
While the colors present on a single piece of tile will be indicative of the colors to be expected on other tiles, the amount of colors on each piece may vary significantly. The minimal color on one piece may be the dominant color on the next piece.
V4: Substantial Variation
Random color distances from tile to tile, so that one tile may have totally different colors from that of other tiles.
