A tile having a contrast pattern intermixed with a portion of a background pattern. The contrast pattern is positioned proximate a selected corner of the tile and has a contrast color different than the colors of the background pattern. Within a surface covering, the rotational position of the tile can be varied to thereby achieve a desired visual appearance with respect to the contrast patterns of adjacent tiles.

The system of claim 1, wherein the plurality of carpet tiles are substantially similar. 3. The system of claim 1, wherein the corner-oriented contrast pattern region of a first carpet tile at least partially abuts the corner-oriented contrast pattern region of an adjacent carpet tile. 4. The system of claim 1, wherein the corner-oriented contrast pattern region of a first carpet tile is spaced from the corner-oriented contrast pattern region of an adjacent carpet tile. 5. The system of claim 1, wherein the first portion of a first carpet tile at least partially abuts the first portion of an adjacent carpet tile. 6. The system of claim 1, wherein the first portion of a first carpet tile is spaced from the first portion of an adjacent carpet tile. 7. The system of claim 1, wherein a first carpet tile is positioned in substantial alignment with adjacent carpet tiles such that the corresponding edges of the tiles are axially aligned. 8. The system of claim 1, wherein a first carpet tile is offset from at least one adjacent carpet tile such that the corresponding edges of the tiles are offset from one another. 9. The tile of claim 1, wherein the contrast pattern further comprises a plurality of yarn tufts, and wherein at least some of the yarn tufts of the at least one contrast color have a height greater than at least some of the yarn tufts of the at least one color of the at least two colors of the background pattern proximate the yarn tufts of the at least one contrast color. 10. The tile of claim 1, wherein the second portion further comprises a plurality of contrast patterns intermixed with at least one color of the at least two colors of the background pattern. 11. The tile of claim 1, wherein the background pattern comprises a majority color and a minority color. 12. The system of claim 1, wherein the area of the first portion of the carpet tile is substantially equal to the area of the second portion of the carpet tile. 13. The system of claim 1, wherein at least a portion of the contrast pattern extends to the first side edge, the second side edge, and the first end edge. 14. The system of claim 1, wherein the carpet tile is substantially rectangular. 15. The tile of claim 1, wherein the contrast pattern has a speckled appearance. 16. The tile of claim 1, wherein the contrast pattern is randomized. 17. A method for forming a floor covering, the method comprising: selectively positioning a plurality of substantially similar carpet tiles, each carpet tile having first and second end edges and first and second side edges, the distance between the first and second end edges of the carpet tile corresponding to a length of the carpet tile, the distance between the first and second side edges of the carpet tile corresponding to a width of the carpet tile, the first and second end edges being joined to the first and second side edges at four spaced corners, each carpet tile comprising: a first portion and a second portion, wherein the first portion comprises a first trapezoidal section and the second portion comprises a second trapezoidal section, wherein the first portion and the second portion are partially defined by a diagonal boundary line extending across the width of the carpet tile from a first position on the first side edge of the carpet tile to a second position on the second side edge of the carpet tile, wherein the first position on the first side edge is spaced from the first end edge by a first distance, wherein the second position on the second side edge is spaced from the second end edge by a second distance, wherein the first distance is substantially equal to the second distance; and wherein: the first portion comprises a background pattern comprising at least two colors;the second portion comprises a contrast pattern intermixed with the background pattern, the contrast pattern comprising at least one contrast color different than any one color of the at least two colors of the background pattern and at least one color of the at least two colors of the background pattern; andwherein the combined first portion and second portion cooperate to form a carpet tile having a corner-oriented contrast pattern region; andwherein the plurality of carpet tiles are positioned relative to one another such that the corner-oriented contrast pattern region of each carpet tile has a particular orientation relative to the corner-oriented contrast pattern regions of adjacent carpet tiles, and wherein the plurality of carpet tiles are configured to cooperatively define at least a portion of a floor covering. 18. A carpet tile system, comprising: a plurality of carpet tiles, each carpet tile having first and second end edges and first and second side edges, the distance between the first and second end edges of the carpet tile corresponding to a length of the carpet tile, the distance between the first and second side edges of the carpet tile corresponding to a width of the carpet tile, the first and second end edges being joined to the first and second side edges at four spaced corners, each carpet tile comprising: a first portion and a second portion, wherein the first portion comprises a first trapezoidal section and the second portion comprises a second trapezoidal section, wherein the first portion and the second portion are partially defined by a diagonal boundary line extending across the width of the carpet tile from a first position on the first side edge of the carpet tile to a second position on the second side edge of the carpet tile, wherein the first position on the first side edge is spaced from the first end edge by a first distance, wherein the second position on the second side edge is spaced from the second end edge by a second distance, wherein the first distance is substantially equal to the second distance; and wherein: the first portion comprises a background pattern comprising a first tuft height;the second portion comprises a contrast pattern intermixed with the background pattern, the contrast pattern comprising at least one contrast tuft height different than the first tuft height of the background pattern and the first tuft height of the background pattern; andwherein the combined first portion and second portion cooperate to form a carpet tile having a corner-oriented contrast pattern region; andwherein the plurality of carpet tiles are positioned relative to one another such that the corner-oriented contrast pattern region of each carpet tile has a particular orientation relative to the corner-oriented contrast pattern regions of adjacent carpet tiles, and wherein the plurality of carpet tiles are configured to cooperatively define a least a portion of a floor covering. 19. The system of claim 1, wherein the first portion comprises a boundary zone, the boundary zone corresponding to the portion of the first portion positioned within a predetermined distance of the boundary line, wherein a portion of the contrast pattern extends from the second portion into the boundary zone of the first portion. 20. The system of claim 19, wherein the carpet tile is square. 21. The system of claim 20, wherein the ratio between the length of the carpet tile and the predetermined distance ranges from about 2:1 to about 20:1. 22. The system of claim 20, wherein the ratio between the length of the carpet tile and the predetermined distance is about 3:1. 23. The system of claim 20, wherein the ratio between the width of the carpet tile and the predetermined distance ranges from about 2:1 to about 20:1. 24. The system of claim 20, wherein the ratio between the width of the carpet tile and the predetermined distance is about 3:1. 25. The system of claim 20, wherein the ratio between the length of the carpet tile and the first distance and the ratio between the length of the carpet tile and the second distance both range from about 1.2:1 to about 10:1. 26. The system of claim 20, wherein ratio between the width of the carpet tile and the first distance and the ratio between the width of the carpet tile and the second distance both range from about 1.2:1 to about 10:1.
