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.
