Your standard bulbs have been secretly replaced.

I see a difference. But I also see a difference in color between incandescent bulbs and normal sunlight. But that doesn’t come up in normal conversation unless you’re an interior decorator or something, because we’re used to that. I’m getting used to the difference in color between the familiar light sources and our new CFLs, too.

(Actually, this far north, “normal sunlight” comes in a variety of colors, too - the light of the low winter sun isn’t exactly like the light of the higher, brighter, summer mid-day light… but again, we’re used to that.)
