The issue isn't so much the color temperature; it's more about overall color rendering. Black-body radiation, like we get from the sun and incandescents, provides the best color rendering across the whole visible spectrum, assuming a color temp somewhere near the middle. CFLs aren't too great at rendering, because their phosphors emit very spiky output. LED phosphors are improving rapidly in this area.
