If you feel your bathroom needs a little makeover, you may have fears that it will require a major overhaul and that it may take an expensive project to turn it into a bathroom you can be proud of and these fears are perfectly normal, although it really doesn't have to cost you an arm and a leg. On the contrary, often a new, fresh look is all it takes. You'd be surprised at how much difference a simple change in colour scheme might make. Often a new coat of paint is all you need. However, you can't just experiment with your favourite colours; there are some rules and guidelines to follow. Luckily, there's plenty of professional advice to be found for free. Thinking about changing the look of your bathroom? Here are some top ideas for the best colours to use.
The colour wheel - The colour wheel is a great help it will immediately help you decide which colours complement or contrast each other. For example, you'll find green 
and blue next to each other (because they are analogous) whilst you'll find yellow and purple on opposite sides (because they contrast each other, allowing you to make fun or bold statements). The colour wheel can give you plenty of inspiration, so get one.
The golden rule of design pick 3 - In many areas of design, the golden rule of 3 is used: pick three colours, one as main (background), one as highlight or contrast, and one as accent. They are usually used in a ratio of 70%, 20%, and 10%, respectively. Think of a man's suit: 70% main (jacket), 20% highlight or contrast (shirt) and 10% accent (tie).
Contrast - If you want your bathroom to be more playful and energetic rather than calming or restful, use two bright or bold colours that contrast each other (check the colour wheel).
Don't fear the dark - Dark colours can help you create a warmer, richer feeling and mood. Don't fear the dark - experiment in design.
Focus on the furniture - You may be tempted to overdo the walls, but remember that they count as background. Focus on the furniture, decorations, and accessories - let them shine, too. It's always a good idea to bring in a little nature to your home, there's something in it that appeals to our basic instincts, and natural colours such as blue, green, and brown tend to calm us down. This is especially true when it comes to the bathroom, so don't be afraid to experiment with nature-inspired hues. Creating a new environment doesn't have to be expensive; it's something you can do yourself, in an economical way, and that can be a lot of fun.
