If you don’t want to paint your cabinets then paints the walls behind them. You can really open a space up by taking the doors off high cabinets and leaving them open for accessories. Painting the backs to match the walls will make them really stand out.
If your kitchen is big enough you can completely change the look of it by adding an island in the middle. You can easily create one yourself by putting two chest of draws back to back and adding a square of solid wood for the top. Make sure to screw it all together and then you're ready to paint it to match the rest of the kitchen. It will look best if the top of the island matches the colour of your other surfaces and the bottom matches the walls or cabinets.
Something as simple as changing the blinds or curtains in the kitchen can give it a new look. You don't have to spend a lot of money, you can buy cheap blinds that are still good quality from any good online retailer. If you have curtains you can change the fabric to create a different look. For a softer look try voile curtains on curtain tracks. These are great because they don't block a lot of light but still give you shade. This is best for small windows as normal curtains can make the room look too dark.
You can also change your light shade by sticking fabric of your choice to the outside. Fabrics that aren't linear are best as it can be difficult to get the two ends to match up otherwise. Make sure the colours in the pattern match up with the rest of the room. You can add cushions out of the same fabric to chairs in the room as well.
Don't forget to add personal touches to the kitchen like ornaments. Fruit bowls are great and functional. You can get them in any shape, size or colour so you're bound to find one to g with your new colour scheme. A tiered cake stand is a nice touch in the kitchen and can look very chic. Again, there are many styles to choose from so you're guaranteed to get one that looks great.
