Interior Colours can change your mood

Blue
Blue is said to bring down blood pressure and slow respiration and heart rate. That is why it is considered calming, relaxing and serene, and it is often recommended for bedrooms and bathrooms. Blue is known to have a calming effect when used as the main color of a room. Go for softer shades of blue. Dark blue has the opposite effect, evoking feelings of sadness. So refrain from using darker blues in your main colour scheme. Stay with the lighter shades of blue to give you and your loved ones a calm effect.
