Common Light Sources
Warm vs Cool Light
Warm light (1000–3500K) has a reddish-orange hue, like candles or incandescent bulbs. It creates a cozy, relaxing atmosphere and is popular in bedrooms and restaurants.
Neutral light (3500–5000K) appears white and is close to morning daylight. It's used in offices and kitchens where clarity matters without harshness.
Cool light (5000–12000K) shifts toward blue-white and mimics overcast sky or open shade. Photographers use higher values to calibrate cameras for blue-sky conditions. Screens typically display around 6500K.
The Kelvin scale describes the color of light emitted by a theoretical "black body" radiator when heated to that temperature — counterintuitively, higher Kelvin = "cooler" (bluer) in visual perception.
