A common mis-conception.

Color temperature is ONLY the ratio of red to blue light. It knows nothing about green.

The problem with fluorescents is that they exhibit excess green as compared with the spectrum of "hot" lights like tungsten or the sun. The only solution to this problem is to use a magenta filter (which is minus green), or a filter specifically designed to correct the excess green.
