Darker Grouts are preferred for floor tiles in a high traffic area, as they will hide stains from accidents such as grease splatters. Lighter grout is generally preferred for wall areas, especially ones that are frequently cleaned and where lighter tiles are used. Consider the colour scheme of both the tile and the area in general. It is also important to take note of what edge your tile has. Pressed edge tiles will show more grout, which can be used as a design feature with contrasting colours. Rectified edge tiles will show less grout and have a more seamless look
