The warm bulbs can make colors look darker or have a yellowish cast example white.
Cool light bulbs vs warm. Soft white 2700 to 3000 Kelvin is warm and yellow the typical color range you get from incandescent bulbs. Cool white bulbs fall in the range of 3100K to 4500K. With colour temperature the higher the temperature the cooler the light.
Warm White 3000 to 4000 Kelvin is more yellowish-white. Home Depot has these light bulbs in Daylight which casts a much cooler light. The warm bulbs can change the color of your cooler tones.
Lets take a closer look at cool white vs warm white LED bulbs. Whereas a daylight white LED light has a cool colour temperature of 5700K. Warm white is a more comfortable white color that is mostly used in living and residential areas.
Take a look at the color temperature. To differentiate between the two the Kelvin scale comes in handy. Cool white light contains more blue light and looks brighter to the eye this is why cool white bulbs have a higher lumen output when compared to the equivalent warm white bulb.
A decorative globe with a vintage-look has a warm colour temperature of around 2400K and gives off a soft yellow light. Warm white is usually around 3000K and cool white around 5000-6000K. However as mentioned earlier everyone has different tastes.
Warm lighting emits a colour that is nearer to natural reddish lighting while cool lighting looks artificial somewhat bluish. Warm whites have a yellow tone which is considered a warm color. Warm lights have lower color temperatures and therefore appear more yellow while cool lights have higher color temperatures and appear whiter or bluer.
