That's one advantage CFL's have over CCFL's. They now come in a warmer color. My uncle uses CFL's throughout his house and I can't really tell a difference between them and incandescent. Plenty of light at low power consumption cost. The color is warm but bright.
CFL's are very efficient compared to pretty much all other forms of lighting that can be used fairly easily in the home, but they are not as efficient as CCFL's.
Here's the chart from Otherpower.com with the addition of other lighting. I found the extra information on the net so question some of its accuracy.
LPS lights--200 lumens/watt (poor color rendition)
HPS lights--140 lumens/watt
HID lights--100 lumens/watt (have horizontal/vertical position issues)
All three of the above are not really suitable for home interior lighting because of their size except HID's but presently HID's are kind of touchy about how they are oriented.
cold cathode fluorescent lights--75 to 90 lumens/watt
32 watt T8 fluorescent--85 to 95 lumens/watt
standard F40T12 cool white fluorescent--60-65 lumens/watt
compact fluorescents--low 30's to low 60's lumens per watt, usually 48-60
LED's (new technology) are reaching 50 lumens/watt
T3 tubular halogen--20 lumens/watt
white LED--15-19 lumens/watt
standard 100 watt incandescent--17 lumens/watt
incandescent night light bulb (7w)--6 lumens/watt
incandescent flashlight bulbs--dismal, less than 6 lumens/watt
T8 fluorescent's look very promising. There are two issues with them to deal with though. First, they run fairly warm to hot like any standard fluorescent and two, they are 1" in diameter so they do take up more space like a standard fluorescent. They do come in a neutral color though so color rendition is fairly good.
I haven't been able to find any company making CCFL's for home lighting use. Or at least not for primary use. Most are for internal PC case display, car accent displays, back lighting for LCD displays, some cabinet displays because of the very low heat generated and things along those lines. None yet for actual home or office primary lighting use. Well not entirely. I did find one desk lamp that uses a CCFL lamp and I did find one lamp that was a spiral CCFL encased inside a clear bulb that was shaped exactly like an incandescent bulb. It was 240v/7 watts.
I was thinking about tossing in a yellow CCFL with two whites to see what the mixed color would produce. The blue really doesn't bother me though.
Now that I've connected the lamp up to a power supply that exceeds its needs and pretty much doubled the light output I'm very pleased with the results. After power on it takes about 15 to 30 seconds for the CCFL to come up to full output. Once it does though it's very bright. I can now say that this one 12.65 watt lamp is producing more light than a single 40 watt bulb with ease.
I'm going to continue my experimentation (playing) and am looking into designing a few replacements for my incandescent lights in the house. It's going to be interesting to also calculate the cost break point compared to incandescent lights.
