For halogen bulbs, you don't need to worry. Now, however, there is a much wider range of light bulbs available. This is because incandescents, long the standard, are on the "warm" end of the light spectrum.

Warm bulbs are rightfully liked for illuminating human faces. Until the last ten years, all light bulbs would have been considered "warm". In other words, the light has a reddish tinge to it. Human skin looks warm and healthy under warm light. As a consequence, if you want to have warm bulbs, you'll need to look for them specially. While they are not quite as warm as incandescents, they are still a very warm light.

For fluorescent light bulbs, the trick is to look at the packaging, to make sure that the bulbs say that they are either "warm white" or "soft white".

In fact, it was only a few years ago that LEDs produced any white light, let alone a warm white light. These are intended to mimic the lighting. Incandescents are losing their dominance, while fluorescent, halogen and even LED bulbs take over the market (in fact, incandescents have even been banned in some jurisdictions).

LEDs currently are not available in a warm light.
