What is color temperature and why does it matter?

Color temperature, measured in Kelvin (K), describes the warmth or coolness of white light. Lower values (2,700-3,200K) produce warm, amber-toned light similar to incandescent bulbs or candlelight. Higher values (5,600-6,500K) produce cooler, bluer light similar to daylight. Standard tungsten stage lighting sits around 3,200K. Daylight-balanced fixtures and film/TV lighting typically target 5,600K.

Color temperature matters when mixing different light sources (tungsten fixtures with LED fixtures, stage lighting with venue house lights) and when lighting for camera. Mismatched color temperatures create visible color shifts on camera that look unprofessional. Most modern LED fixtures and moving lights include variable CTO/CTB controls that let you dial in a specific color temperature to match other sources in the space.
