The Properties button in the Texture area allows you to manipulate the selected texture for that color number.
The Scale of the texture may be modified to make it as photo-realistic as possible.
The texture pattern used may also be set up to repeat in a Mirrored or Tiled fashion. Mirrored allows for a pattern to repeat with fairly smooth joints where a tiled texture appears more segmented. The choice will depend on what texture is being applied and how large the object is.
Note: Textures can be applied to something as large as a carpet or as small as a chair arm so the pattern and repeat will vary.
