For dielectrics (non-metals), this specifies diffuse reflectance for opaque materials, or transmission color for transparent materials. For conductors (metals), this specifies reflection color. Complex IOR specifies the color of a metal with an IOR value of "n", and an extinction coefficient of "k". IOR is the index of refraction, which controls both the reflection, as well as the refraction, of a
