Carpet tiles having patterns and color schemes that obviate the need to orient the tiles in a particular positional or rotational relationship relative to each other. The tiles exhibit orthogonal ambiguity, meaning that they may be laid in any side-by-side orientation with respect to adjacent tiles without looking out of place to the ordinary viewer and thereby still achieving an appearance of continuity like broadloom carpet. Each tile has patterns of shapes having some straight and curved elements. At least some of the straight elements on each tile preferably parallel a tile edge. The shapes are formed from a color or combination of colors so that adjacent shapes on each tile have at least one color in common. Furthermore, each tile has at least one color in common with every other tile, so that when the tiles are laid, the colors on adjacent tiles coordinate. Moreover, because the pattern on each tile appears random, placement of the tiles on the floor in any side-by-side orientation simply creates a larger, apparently random pattern, rendering it impossible for any tile to look out of place.
Carpet dies comprising tile edges and textile faces, each face having a pattern comprising a plurality of shapes having shape edges, wherein:
Carpet tiles cut from a carpet web comprising a web face having a web pattern comprising a plurality of primary shapes formed by a plurality of colors, wherein at least some of the plurality of primary shapes each comprises at least one curved side and is at least partially partitioned by at least one line to form secondary shapes comprising at least one curved element, the tiles cut from the web comprising a common color and each having a tile pattern, wherein the tile pattern of at least some tiles cut from the web comprises:
