Listen to the space
When selecting a color, consider the "mood of a room. For example, in a bedroom do you want the feeling to be restful and soothing or dramatic and intimate? Soft, cool colors and neutrals usually create a quieter feeling while stronger colors are for drama. Do you want a dining area to feel sociable and stimulating, or cool, formal and quiet? Warmer, contrasting and somewhat brighter colors add to a sociable atmosphere; deeper blue-greens and neutrals will give a more formal ambiance.
Do you want the childrens areas to create an active and sociable energy, or a feeling that is orderly and restful? Avoid the temptation to overstimulate.
Light up your life
The quality and source of lighting can make all the difference in a room. Natural daylight shows the truest color. Incandescent lighting brings out warm tones and yellows, while fluorescent lighting casts a sharp blue tone overall. A strong color might be too bright and overpowering when used on all walls or next to a large window, but it might be effective when used as an accent wall with indirect light.
