Different lightbulbs alter paint color perception; daylight LEDs emit cooler tones that can make colors appear harsher, while warm LEDs provide a cozy yellow glow. Mixing bulbs creates inconsistent color readings in a room. For consistency, choose bulbs with the same color temperature, ideally around 2700 Kelvin for a warm, true-to-paint appearance. This uniform lighting helps your paint color display as intended without surprises or repainting later.
