Reply To: Mixing “Principled BSDF” and “Translucent BSDF” an artistic decision?

There is no transluscent setting on the Principled BSDF, and transmission is something different entirely, but yes the color of it is certainly an artistic decision. Translucency (as defined by the Blender node, not by the dictionary) is just diffuse with the light appearing on the opposite side of the normal. You can’t see through it. Transmission is essentially just refraction and you can see through it. The roughness value blurs those refractions but the light is still coming through. Here’s an example of rough transmission, translucency, and diffuse side by side.
