The Floor: Light coloured floor covering will certainly help you to achieve you objective. As a result, if you plan on using ceramic tiles, choose those which are medium in size for instance around 6' 8 inches that has an easy pattern and obviously a light shade as smaller sized tiles can help to make the room seem small. You could use a big light coloured area carpet to cover up your dark flooring if this is your case if your budget can not cover you changing your flooring.
