Most CFLs (and all new Energy Star CFLs) now put out a light in the same color range as incandescents. Color for lights is specified on the package, sometimes in degrees Kelvin, or “K”. Look on the package for the “K” rating. The table below translates degrees Kelvin into human-speak, just in case the packaging does not. You can also get them in bug light yellow, party green and probably other festive colors.

 
Color See "color temperature" on packaging, rated in Kelvin (K)
Warm, for general illumination (color same as incandescent)2700-3000K
Cool, for kitchens, workrooms, utility rooms3500-4100K
Daylight, for general illumination5000-6500K
