But, using a warm light bulb like that leaves a lot of color spectrum out of the picture. They make bulbs that are 4100K, 5000K and 6500K balanced. If I were going to be shooting with fluorescent, I'd likely be using the 6500K (i.e. daylight/full spectrum) variety.
Be careful not to confuse color temperature and CRI (Color Rendering Index). They are representations of two different things.
There can be a light source with a low color temperature (eg3200K) that has a high CRI. Tungsten bulbs fall in that category, they are great light sources. Other sources, such as certain fluorescent lights, can have "daylight" color temperature, yet have horrible CRI. These make poor light sources because even the the color temperature can be set, not all colors will be rendered properly.
See this description of CRI. Notice the photograph on the right. You can see that the spectrum from the incandescent light has a smooth spectrum, whereas the CF bulb has missing bands. It does not emit light in that area of the spectrum. You can get an approximate color balance, but you can't fill in the holes.
