"All I know are these new light bulbs suck. I have difficulty reading under them."

Then you're not buying the ones with the appropriate spectral output. The article is pretty simplistic in its description of CFL's. There are several varieties with different "color temperatures". The normal CFL's have more blue emission, but there are "warm white" versions that duplicate incandescent spectra more closely.

None of the CFL's have a continuous spectrum like an incandescent. The color values of an object depend on the integrated reflectivity over the spectrum, so there will inevitably be differences in color appearance among objects which appear the same color in natural light, which of course is incandescent. There are "holes" in the CFL spectra, and these will match up differently with the reflectivity spectra of various objects.
