Although orange may seem rather 1950ish to some people, it has actually come back into style. Be careful though because too much orange can make people nauseous. Using bright orange to punch a colorful hole into an otherwise drab environment can make a delightful impact. By applying softer oranges, you can create an atmosphere of freshness. The kitchen is a wonderful place to use the color orange, as long as it's not overdone. A wonderful choice for a focal point, orange decor can lift the spirits.
Because orange tends to be an action color, it's best used in areas where you like to be motivated to get things done. A cheerful splash of orange in your laundry will help lift your mood when you need to complete the drab job of ironing or folding clothes. A work desk area is another great place to display some orange to help motivate you to get those bills paid or answer the deluge of emails on your computer.
I highly recommend you don't use orange in a child's bedroom, because you want your child to sleep, not be motivated to action in the bedroom. Children who suffer from ADD or ADHD are especially agitated by too much of the color orange. A child's playroom is a great place to use orange in limited amounts. If you've never decorated with orange before, it's best to start in small amounts. Combining orange with yellow will increase the action feeling of it. Combining orange with green will make it feel a bit more outdoorsy. Combining it with a light blue will help soften the impact of orange. No matter where you choose to decorate with orange, you'll likely find yourself drawn to that area when you need a boost of energy!
