The colour of purity and the most light reflective of all colours, white makes a great base in a home. Though as anyone trying to colour match knows - there are thousands of shades of white! The good news however is that for an all-white look, it is the mixing of shades and textures of white which makes it work - and you can add an accent of any colour and have it look good.
White curtains on a white wall are a great option if you have stunning views and want to focus on that rather than the interior of the room.
