well some of them are. If you like a particular brand and model I'd stick to that. There are still tons of the "warm white" with a color temp of like 2700k or some of the off brands even 2400k which are not only yellow like a regular bulb but green as well.
I really like the 3100-3500k ones (which are sometimes now branded as "bright white") and 4500k for work lights and shop lights type things. But I can't do the blue ended "daylight" ones.
So be sure to buy lights that either print the color temperature on them, or that you already know you like. THere is a tremendous variation in the colors available out there!
