Shade variation

The shade of tiles within the same production run may vary significantly from piece to piece, so a standard scale has been established to indicate the degree of such variation for each tile model.

	V1	Uniform appearance	Minimal to no differences between pieces from the same production run.
	V2	Slight variation	Slight color differences between pieces from the same production run.
	V3	Moderate variation	While the color on a single tile is indicative of the color of tiles from the same production run, the color on other tiles may vary significantly.
	V4	Substantial variation	Tiles from the same production run have random color differences.
