Color tuning is the technique of adjusting of the color of electric lighting in a space. More complex than dimming, color tuning further enhances the ability of lighting to dramatically change the look of a lighted space. While dimming simply results in more or less light, color tuning actually changes the appearance and "feel" of color. Used together, dimming and color tuning proide a way to greatly expand lighting's role in a person's visual and emotional experience.
According to Lutron Electronics Company, as LEDs (or solid-state lighting – SSL) becomes more advanced, new technologies allow LED color to be adjusted almost infinitely to deliver the perfect light. Color tuning can be warm dimming, tunable white or full-color tuning. More information about color tuning is available on Lutron’s website.
