Demystifying Color Temperature: A Primer
Before we dive into the nitty-gritty of 4000K vs. 5000K, let’s get back to basics. What exactly is color temperature, and why should you care?
What is Color Temperature?
In a nutshell, color temperature measures the color appearance of light. It’s measured in Kelvin (K), and the higher the number, the cooler (or bluer) the light appears. Think of it like a thermometer for light:
- Warm White: 2700K or 3000K (think cozy candlelight)
- Neutral White: 4000K (a balanced, crisp white)
- Daylight White: 5000K or 6500K (bright, like midday sun)
Our contenders, 4000K and 5000K, fall into the neutral and daylight categories, respectively.
