No brand recommendations, but the warning that it's less the color temperature (though that IS important), but the spectrum consistency that'll cause problems. Spiky spectrum response lighting (aka inexpensive fluorescents) will make color matching extremely difficult, especially with a pigment-based printer.
Solux, Just Normlicht, GTI, are the classic brands, with ott-lite a relative newcomer (and lower priced option). None are cheap, though.
If you don't need D50, but can deal with D65-ish, there's a bunch of high CRI fluorescent tubes that might work. Lumichrome (CRI=96), Vita-Lite (CRI=96), Osram's Biolux (CRI=97). There are some 5000K fluoro tubes with high CRIs, but they're less common. Philips' HI-VISION F32T8 (CRI=98) is one of the more available ones.
And warmtoned or cooltoned walls will also have an effect.
