Lamp geeks will talk about color temperature in degrees Kelvin, like
"2800 K". Fluorescent lamps are sometimes marked this way, but sometimes
they use a code like "28" for 2800 K, "30" for 3000 K, and sometimes
aren't marked at all.


Check again, now. Most of the fluorescents I see at Lowe's DO have the
Kelvin temperature on the package.

I was at Home Depot the other day and it was indeed marked on most of
the CFLs they sold. It wasn't on the front in the little "lumens/watts/
hours" box (where I think it should go), but it _was_ printed on the back.
The "nvision" brand had three different color temperatures available and
the packages were printed in different colors on a white background. IIRC
red was "soft white" and about 2800 K; green was "bright white" and about
3500 K, and blue was "sunlight" or "daylight" and about 5500 K.
