Thanks for that...I'm not an expert but lets see if I can come up with something similar.

 

edit to add: Fresnel blend looks similar to an edge blend brick. I'm wondering if the index of refraction does the same as attenuation? Attenuation appears to increase or decrease the amount of graduation between the two colours.

Hope I'm explaining that properly.

 

Also can you explain what the alternate diffuse does? I'm wondering if I can achieve the same effect by adding in an additional mix brick...
