The Philips Hue White Ambiance Cher Suspension light is shown here. You can buy fixtures with color-tunable light as well as light bulbs for your existing luminaires. “The color paint you pick under the fluorescent bulbs at a hardware store might look very different when you get it under the light bulbs you have at home,” says Cory Bergeron, an author and video production professional. This is why designers advise you to place lighting elements and choose bulbs before you paint and furnish a room. That same wall under a 2500K light source may look yellow. A wall that is white under a 3200K light source can look green under a 4000K light source. If you’ve ever replaced an incandescent light bulb with a fluorescent bulb and remarked about how cold, off-putting, or downright ugly the room looked after your upgrade, you’ve experienced how dramatic an impact color temperature can have.Įverything in a room is impacted by the light source in that room. Matching color temperature to your environment It is only the visible portion of the energy emitted by the sun that we detect as light that approximates its color temperature rating. The color temperature of the sun is measured at about 5600K, but the actual sun itself varies in temperature widely (and reaches into the millions of degrees internally). The terms warm and cool aren’t intended to describe the actual temperature of the flame used to produce the light but rather the aesthetic these lights generate.Īs well, color temperature ratings aren’t always entirely meaningful on their own. The use of the terms “warm” and “cool” is a bit paradoxical because, when examining the Kelvin scale, you’ll see the “cool” light is actually hotter than “warm” light. LEDVANCEĪ bulb that emits “cool” light is the best choice for task lighting. Professional lighting like that used by photographers and filmmakers can vary well beyond this narrow range and can even mix various colors of lights together in a single device. Different bulbs produced with different materials and with different techniques will vary widely in their color temperature.

Note that these are all estimates and averages. Standard fluorescent lighting is typically produced at this color temperature, and it’s what you’ll find in most business environments, as light at this wavelength is considered ideal for reading and other detail-oriented task work. At about 3500K we enter the realm of “cool white” or “bright white.” Lamps at this color temperature take on a more neutral color and may appear to have a slight blue cast.
