Choosing Lighting with Color in Mind is an Important Decision.
You can make appropriate lighting choices that consider light and color in your home!

Important Information

Color Rendering Index:
Describes the way light makes colored objects look.

• For example, incandescent (97-100 CRI) has an excellent color rendering index!

Color Temperature:

Described the way the light source appears.

• For example, the color temperature of incandescent light is warm, about 2700 degrees kelvin. Other sources are cooler. Some fluorescent lights are about 4000 degrees kelvin.

Purchasing:

• Carefully read the package before you purchase the bulb. The package will tell you the color rendering index and color temperature.
• Be sure to purchase light bulbs from a reputable manufacturer.
• Spending a little extra time at the store can save you aggravation when you get home!

When Thinking of Light and Color, Consider...

Appearance: 

• Different light sources may affect colors. For example, the same color might look different when viewed under incandescent and compact fluorescent lights.

Color Critical Areas:

• Lighting affects color. Color critical areas include dining rooms, family rooms, bathrooms, closets, bedrooms, laundry rooms, craft and hobby areas, and places where art is displayed.

Initial Cost:

• How much will the light cost when you first buy it?

Control:

• Dimming might change the color of some lights. For example, dimming incandescent lights makes the light appear more orange.

Remember:

• Lighting can produce warm or cool atmospheres. For color sensitive activities, such as applying make-up and selecting fabrics, consider warm light.
• The color of daylight varies at different times of the day, across seasons, and in geographic locations.

Lighting can ... 

• Create a cohesive “warm” or  “cool” look in your home
• Make skin tones look more natural
• Help you closely match colors (for dressing, sewing, arts and crafts, or laundry)
• Enhance colors in your home

Consider how the color rendering index and the color temperature affect your home.
