How are Ceramic and Porcelain Tile Graded for Color Variation?
The variation of color, texture, and tone between individual ceramic and porcelain tiles is known as color shade variation. An inherent characteristic of any fired product, variation in color and shade can actually enhance the character and beauty of the finished project.
Within each style, and even within each production run, color shade can vary to differing degrees between each tile. While many products have little to no variation, there are options that display a moderate to dramatic range of variation – each is a stylistic choice. Here’s a breakdown of how ceramic and porcelain tiles are graded for color shade variation:
V1-Uniform Appearance: Minimal to no difference among pieces from the same production run because each ceramic tile is manufactured using the same glaze applications and body texture.
V2-Slight Variation: Distinguishable differences in texture and/or pattern within similar colors.
V3-Moderate Variation: Though the colors present in a single piece of ceramic tile may indicate the color patterns to be expected on other tiles, the amount of colors on each piece might vary significantly.
V4-Random or Dramatic Variation: Random color variation from tile to tile, so that one ceramic tile may have a totally different color from that on other tiles. Thus, the final installation will be unique.
To make sure that you get the look you’re after, find out how much color shade variation the tiles have before you make a purchase. Reviewing several pieces from the same production run is recommended to help you decide on the acceptable color shade variations. Most often you can look at your tile choice’s technical specifications to find out the grade of color shade variation assigned that product.Do you want all your tiles to look the same or would you like some variation?
