The light color of a lamp is also called the color temperature and is expressed in Kelvin (K). The lower the Kelvin the warmer the light, the higher the kelvin the cooler and more white/blue the light will be.
For example, you can choose from very warm light (1700K - 3300K) which is suitable when you want to have a warm and cozy atmosphere. Cool white light is suitable for general lighting (3400K-5000K) and light with the light color daylight (6500K) are suitable for specific purposes where a lot of natural light is needed.
