Selecting a Colour
Red or pink tones look deeper and richer in artificial light, but blues and greens can look washed out. Keep this in mind when choosing colours for a room that will be used primarily in the evenings.

Colours have characteristics that can affect our mood and make the same room appear completely different, simply by the way it is decorated. So before you begin to think about colours, take a good look around the room and make a note of how much natural light it gets and what you like or dislike about it.

Warm colours such as red, orange and yellow are 'advancing' colours which appear to draw surfaces closer, and create a sense of cosy comfort. These are lively colours, which make them a good choice for gloomy rooms facing north or east which receive little natural light, basements, and rooms heavily shaded by trees.

Cool colours such as green, blue and violet are 'receding' colours which maximise space, and make a room feel fresh and airy. These are relaxing colours ideal for sunny rooms facing south and west, or anywhere there is abundant natural light.

Neutral colours such as cream and beige are useful for toning down more adventurous colours but, used in their own right, will allow attention to be focused on the contents of a room, rather than the room itself. They also complement natural woods and cork well.

Some colours evoke a definite mood which makes them a good choice for particular rooms. Pinks and red-blues, for example, have a romantic feel that is perfect for dining rooms and bedrooms, while fresh outdoor colours like yellow and green are best suited to busy daytime rooms.

What colours should I use?
Colours that are opposite each other on the colour wheel, such as yellow and blue, create stimulating colour schemes, while those that are close to each other, like blue and green, harmonise well and are more relaxing to live with

To create light and depth in a room and to make sure that no one colour dominates, use colours in different strengths and add neutral accessories.

Pale colours reflect over 80% of light and dark colours absorb nearly 90%, so a higher level of artificial light is needed in a room where there is a dark or strong colour scheme.

Contrasting colours that clash, like lime and yellow or pink and orange, can create a very dramatic, modern colour scheme, and work best in big bold blocks with nothing else competing for attention.

If you are not a confident decorator, a colour scheme which uses several strengths of the same basic colour is a safe choice and very easy on the eye. Use the mid-tone for a large area like curtains or the floorcovering, a lighter tone for walls and ceiling, and the strongest only for emphasis with accessories.

Using only shades of a single colour can look dull, but the effect is easily spiced up with an accent colour from the opposite side of the colour spectrum. A splash of orange or peach will brighten up a blue room; green makes an elegant contrast to rosy pinks; and yellow adds warmth to a lilac colour scheme. An accent colour needn't be paint or wallpaper - colourful lampshades or cushions will do just as well.

Choosing Patterns
Large and busy designs tend to draw in walls and make big rooms seem cosy, but they will overwhelm a small space. Similarly, tiny or subdued patterns will make the most of small rooms, but get lost in a large one.

Pattern can also create optical illusions and because of its ability to trick the eye, it can be a useful decorating tool if the features of a room aren't pleasing.

Regular patterns will highlight walls that are out-of-true and uneven walls can make pattern matching very difficult, so choose a wallcovering design with care.

Florals don't allow the eye to fix on any one point, so they are wonderful for irregular walls and for softening awkward angles or disguising an unattractive feature.

Dainty floral sprigs are perfect for small rooms, narrow hallways and cloakrooms, whereas big florals are best shown off in large or high-ceilinged rooms, and in bedrooms with co-ordinating fabrics.

Stripes suit almost any style or size or room. Classic stripes in contrasting colours are a good choice for smart daytime rooms and hallways, whereas stylised stripes are more informal and very versatile. Stripes are also useful for altering the proportions of a room. Horizontal stripes seem to push out walls in a small room, and will make a low ceiling appear higher when used vertically.

Trimming wallpaper around doors, windows or cupboards can ruin the look of a large pattern. Stripes and small designs will be a better choice, and more economical on the number of rolls needed.

Checks range from smart tartans to informal ginghams, and are as versatile as stripes but look busier, so they work best in simple colour schemes where the pattern can be fully appreciated. Checks are also useful for drawing in far-away walls and softening harsh edges.

Geometrics are neat and restful, and make walls seem to recede, so they create the perfect backdrop to a busy or cluttered room, or pictures and memorabilia that you want to display.

If you have chosen a stimulating colour scheme, be sparing with pattern on furnishing and accessories. Busy patterns will simply compete for attention.

Mixing Patterns
Pay attention to the size and scale of a pattern, and use large designs over large areas such as a sofa or curtains for a wide window, and keep small-scale designs for accessories like cushion covers and lampshades.

In a large room, don't be afraid to break up walls with pattern and add deep borders for emphasis. In more modest rooms, mix a small pattern with a bolder design, and if you think that a room is becoming too busy, tone it down with areas of plain colour or paint-effect wallpaper.

Decorating a stairwell can be tricky, but dividing tall walls with a dado rail or border and using complementary wallcoverings above and below will make the job easier and add interest.

If you are not a confident decorator, choose wallcoverings and fabrics from a fully co-ordinated collection which will ensure that patterns are evenly balanced and have a similar dominating colour. This allows the eye to flow from one part of the room to the other, and is especially important for open-plan living areas and dual-purpose rooms.

However, if you do want to try mixing different patterns, the key to success is to choose designs that have a common colour and style, and stick to it throughout.

Decorative borders aren't just for walls. They help to integrate patterns, and can be used to jazz up doors, an old pelmet or bedhead, and even some types of furniture.

Introducing Texture
Texture is a subtle way of adding visual interest. Matt, rough textures such as wool, brick, wood and cork add warmth, while smooth, shiny surfaces such as chrome, glass and ceramic tiles are cool and more sophisticated.

Texture can enhance the overall effect you want to create. Matt emulsion, for example, has a rich velvety finish that helps to make big rooms seem more cosy, while the light-reflecting sheen of silk vinyl has a brightening effect that makes small rooms seem more airy.

Texture is very important in one-colour schemes. Where a room has no colour contrast, add rugs and fabrics with a woven pattern for warmth.

Poor surfaces will be much more obvious with a plain painted finish so, if you don't want to add pattern, add texture. Paint techniques such as sponging and ragging will help to disguise blemishes.

If pattern isn't to your taste, paint-effect paper will give walls an instant facelift with colour and texture, but without the skill or effort needed for the real thing.

Starting out
Few of us are lucky enough to start decorating from scratch. There is usually an item that we don't want to replace, and which has to blend in with the new colour scheme.

With plain carpets and fabrics, you can be as bold or as restrained as the mood takes you, but picking colours or patterns to complement existing designs can be more tricky. Take your cue from a shade in carpet or curtains, and use it as the starting point for the new scheme.

Florals look good against an otherwise plain background, while stripes and small geometrics mix well with other patterns and won't compete with more demanding designs. Paint-effect papers are extremely adaptable, and a failsafe choice.

Finishing touches
Don't forget to update accessories such as picture frames and table lamps to complement your new colour scheme. If you can't afford to buy, it is possible to paint many surfaces with the right preparation.

Lampshades that complement or contrast with your colour scheme are a quick and easy way to create a stylish, co-ordinated look.

Dimmer switches are easy to install but will allow you to change the mood of a room at the touch of a button.
