I´m trying to get this type of material, but changing the refaction color always results in a blueish tone (when using orange as color). Using orange as reflection color results in orange reflections as suspected.
Maybe a bug...
This is an energy conservation issue. Refraction gets what remains after reflection. If your reflection is pure red, you cannot then have any red in refraction, hence you get the complementary color.
I can think of 3 ways to do this:
1) what is currently implemented (strongly colored 1 component results in complementary color in the other
2) darkening of all color channels equally (then you would get no complementary color, but gray/dark).
3) breaking energy conservation (fake)
I dont know what is best. Vray lets you choose IMHO between 1 and 2
