How can I determine the color / temperature of my current fluorescent bulbs?
The temperature will likely be printed on the bulb somewhere. Take a couple out and check, and they are all likely the same. If not, you can compare the color to an image like this:



There is no "standard" for fluorescent lighting, as they come in a variety of temperatures. That said, fluorescent bulbs are more traditionally associated with the institutional bright white light, which would put them on the higher end of the temperature scale (closer to 6700K).
