It is fairly common knowledge that colors are found to elicit and convey specific emotions. A infographic entitled “The Psychology of Color” featured on the home improvement site Freshome.com shows several examples: blue promotes maximum productivity in the home office; green allows for a restful feeling of tranquility and health for bedrooms; yellow gives out energy in kitchens; lavender creates a relaxing atmosphere for living rooms; and red encourages appetite in dining rooms.
Sanders also put emphasis on color combinations. However, he warned people on the risks of using bold colors (especially if they like using such); as the human mind is likely to get tired of them quickly. Such colors are much more ideal as accents rather than as base. Aside from portraying different moods, colors also create significant illusions: lighter colors like white make walls and ceilings look higher; while darker hues create the illusion of lower ceilings and adds more drama.
