Pick your type of white

First of all, you may want to decide the kind of white which will fit your fancy. White may sound like a plain choice, but mind you, there are tons of different types of white paint. There’s the modern white -- a crisp white selected by ultramodern designers. Romantic white – a grey-based white which brings an ethereal presence with it. And, Japanese paper white – a creamy white with warm tones, perfect for wooden-themed rooms.
Use Textured Sheets


An all-whiter is not to be equated to a boring room. To stay true to this, you can integrate different textures into a room to give subtle design varieties. A frilly bed sheet will do the trick for your bedroom design. As for the living room, you can play with texture on throw pillow covers and curtains.
Throw in a pop of color

Break the monotony by getting an accessory that is brightly colored. Take a lead through this bright red bed sheet cover inside a white bedroom.

If you’re trying to keep the delicate feel of white, you can choose to go with soft, warm hue types. Take these earthly tones of light green and gray. Furniture pieces in a different color would be a nice contrast in a white-walled room.
Use minimalist accents

Simplicity brings an irresistible sophistication with it. If this is the look that you are trying to achieve, then you can look for designs with minimalistic accents. Materials with a repeating and plain pattern are easy props to do it.
Incorporate a shabby style


An unfussy way of playing with whites is to incorporate a shabby feel to it. This would be perfect for country cottages, beach houses or for a simple shack. It’s is an amusing way of achieving a rustic with a touch of modern kind of vibe.
Add wooden accents


The genuine look of authentic wooden furniture looks good in a white-painted room. You can take advantage of the natural wood color and make it your theme accent.

If wood doesn’t appeal to you, then you could go modern by sticking with dark accents. Black, maybe?
Display interesting pieces

You can also disrupt the dreary white space by placing unique and interesting pieces in the center of the room. Think of awkwardly-glued pieces of tree branches or exotic flowers. Or a vintage jar that you have brought from your recent Asian trip.
Work with metallic accents

Want to instantly glamor up the room? Play with metallic accents. Get a silver, metallic paint and paint it on a table top. Or use a wallpaper with an intricate, shimmery patterns.
Put up a fantastic light display


Easily turn a white space into an elegant and romantic space when night falls. Plan your lighting system and use different lighting fixtures in your white room. A string of light projected onto the upper edges of the walls can do wonders.
