We have a very nice deep gold wall color that looks fantastic during the day. At night, however, the room turns on you. Our normal CFL illumination would reflect from the walls a very sickly tinge of green -- as in "what did you eat? get to the hospital!". I tried hard to ignore it, but never quite could. In fact, I had gone back to using incandescents for the room, but recently tried a GE Reveal CFL on a whim. Instant room makeover. In fact, we put three lamps: normal CFL, incandescent, and Reveal CFL in three corners of the room one evening for a test. The Reveal provided far and away the best overall color.. a nice relaxing warm gold, somewhat warmer than when daylight illuminated, but with *none* of the sickly green I had long assumed was an unavoidable artifact of CFLs. Now maybe this was an unusual interaction with my wall color, but if you have a case of the greens, these are definitely worth a try.
One minor nitpick: likely due to the different phosphor formulation, they use slightly more power at the same light output. Well worth it (and their additional cost) in my view.
