Here are some examples detailing which colour temperatures may work better in different room types:

Extra Warm White 2700K

Lounges, living rooms and bedrooms. This style of light appears warmer and sets a more relaxing, homely scene. If you think halogen is too warm and want some else then try 3000K instead.

Warm White 3000K

Kitchens, conservatories and bathrooms. The slightly whiter appearance allows you to see better but is not too cold. Although this colour temperature can be used anywhere.

Cool White 4000K

Although I wouldn’t recommend this in lounges, cool white can be used effectively in kitchens. The most popular destination for this colour temperature is bathrooms. In a white bathroom it can make appear brighter and cleaner although if your planning on spending time in the bath it you may want to go for a more warmer appearance.
