Blue

• Blue is a relaxing, clean color that both men and women like for a bedroom or bathroom, says Demesne, a website dedicated to homeowner topics.
  
  

Yellow

• Yellow, warm and sunny, creates a cheerful room, many people believe, while others dislike it.
  
  

Red

• Powerful and exciting, red can even stimulate the appetite. More-muted shades, like brick, create a cozy feeling, while pink tones are soft and feminine.
  
  

Green

• Green, as a color of nature, is seen as soothing and healing. Olive and sage green are more-neutral and thus easier to work into your decorating scheme.
  
  

Orange

• Often used in restaurants for its positive effect on the appetite, orange is warm and friendly. In homes, it works well in kitchens and dining areas.
  
  

Neutrals

• Black--which has a sharp, modern feel--and brown--a comforting, reassuring color--can make a room seem smaller, so they should be used carefully. Grey is stylish and versatile, and because it enhances creativity makes a good color for an office. White denotes cleanliness and sophistication, says My Space Designers, a website dedicated to interior design.
