Warm White vs Cool White vs Daylight: The Ultimate Color Temperature Guide
Have you ever walked into a room and immediately felt “at home” or on the other hand, you felt like you were the focus of a spotlight in a laboratory? The secret isn’t just the furniture, it is decor and it’s the color temperature of kelvin scale also.
In the world of lighting design, there are many “shades” of white light through which to choose your light and the affect [everything] in your living space will take. Knowing what is called the bulb kelvin scale is the first step in creating a home that is not only bright, but really beautiful.
What is the Kelvin Lighting Scale?
Before we jump into the comparison though lets talk science. Kelvin lighting is measured in units that are called “Kelvins” (K). Unlike Celsius or Fahrenheit which are thermal heat scales, the kelvin color temperature scale is a visual “warmth” or “coolness” measurement of a light source.
Imagine that you are heating up some piece of metal. As it becomes hotter and hotter, it first turns a deep red, then orange, then yellow, white, and lastly a brilliant blue. This progression is exactly what the concept of color temperature kelvin scale is:
Low Kelvin (2000K – 3000K) Warm, yellow, and cozy tones.
Mid-Range Kelvin (3100K – 4500K): Neutral Crisp Balanced white.
High Kelvin (5000K – 6500K): Cool, blue-white light which simulates bright daylight
