Colour temperature describes the color characteristics of light, usually measured in degrees Kelvin (°K). It ranges from warm (yellowish) to cool (bluish) tones. The higher the Kelvin number, the whiter the light.
Remembering Colour Temperatures:
- Warm Light: Lower Kelvin numbers (2700-3200K) indicate a yellowish, warm light.
- Cool Light: Higher Kelvin numbers (5500-6000K) indicate a bluish, cool light.
You may encounter descriptions like “Cool white” or “Daylight” instead of specific Kelvin numbers, which can be confusing. Always ask for clarification to ensure the right lighting outcome for your needs.
Colour Temperature and Mood
Lighting color temperature can influence the mood of a space, similar to how paint colors do.
Warmer Colour Temperature (2700-3200K): Creates a cozy, soothing, and calming environment. Ideal for intimate settings such as restaurants or comfortable office spaces.
Cooler Colour Temperature (5500-6000K): Creates a bright, airy, and energetic environment. Suitable for cafeterias, classrooms, lobbies, general offices, and certain retail stores.
Examples of Spaces and Colour Temperature Ranges
- Living Room/Bedroom: 2700-3000K (Warm Light)
- Restaurant/Café: 2700-3200K (Warm Light)
- Office: 3500-4500K (Neutral Light)
- Classroom/Cafeteria: 5000-5500K (Cool Light)
- Retail Store: 5500-6000K (Cool Light)
Choosing the appropriate colour temperature for your space can significantly enhance the desired mood and functionality.
