Yellow - just thinking about it gives me a little boost. Using a splash of yellow in your home decor during the dark short days of winter can help to boost your mood.
Color really can be called the food of our emotions. It can reflect our thoughts and moods without us being aware of it.
Yellow is the color of joyful sunshine. It just says happiness and warmth. There is a reason happy people are said to have a sunny disposition. Sun=yellow=happiness. That's an equation we can all embrace when we decorate our homes.
Too much yellow though is not a good thing. Studies have shown that in a yellow interior people are more likely to lose their tempers. So painting a room a bright yellow on all four walls might be just a little too much yellow.
Using accents of yellow in cool colored rooms will give them a splash of warmth or happiness. Think of photos on the walls, pillows on the couch or a piece of pottery to bring the joy of yellow to a beautifully decorated room.
