I see the differences that you are talking about, and I don't like to mix them in the same vignette, but they don't bother me when apart, even in the same room.
I have lamps with nice linen color shades that give off a different light than my Tiffany style lamps with the various colored shades, (and that is kind of like the same thing) and that doesn't bother me either.
But then I never really thought about the lamp thing until you asked this, maybe it should bother me!LOL
