See previous post for Fake Fresnel. At any point in a shader tree, you can change a node to "mixer" and build out the structure you see there. For the actual color gradient, simply click on the color bar and it will open an edit window where you can build your gradient. Mark

Thanks; will experiment. I also located the Soap Bubble shader mentioned above that came with Carrara. I've not tried your bubble yet, but with the Carrara one, when the bubble is in front of or surrounding a glowing 3d-aura object, the light from the 3d glow does not shine through the bubble. The object itself is visible through the bubble, but not its 3d glow. What's up with that? Jim
