Warm your blue kitchen by switching to 2700 to 3000 kelvin lights with a 90 plus CRI rating. These warm LED bulbs create a cozy atmosphere by softening the cool tones of blue cabinets. Start by replacing existing bulbs with vintage-style warm bulbs and add under-cabinet amber lighting to further enhance warmth. This lighting adjustment alone shifts the mood significantly, helping your kitchen blend smoothly with the rest of your warm-toned home.
