Formula
Classification based on Kelvin ranges: Warm (2700-3000K), Neutral (3500-4500K), Cool Daylight (5000-6500K). Mireds = 1,000,000 / Kelvin.
Frequently Asked Questions
What is color temperature?
Color temperature, measured in Kelvin (K), describes the colour appearance of light. Lower values (2700K) appear warm/yellow, higher values (6500K) appear cool/blue.
What color temperature is best for an office?
Neutral white (3500-4500K) is generally recommended for office environments as it promotes alertness without being harsh.
