Light and Color
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.
Approximate ranges for color rendering index and color temperature for common home interiors light sources
Color Rendering Index | Color Temperature (K) | ||
---|---|---|---|
Compact Fluorescent | 70-82 | 2500-6000 | |
Incandescent | 97-100 | 2500-3000 | |
Light emitting diode | 70-90 | 2700-4200 | |
(Linear) fluorescent | 52-90 | 3000-6500 | |
Tungsten halogen | 97-100 | 2800-3000 | |
Xenon | 95 | 2800-6000 |
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.
Color Rendering Index (CRI)
