How do you get hair to take on the color of the mesh it's attached to? I'm still pretty new to Blender (currently using v2.9), so I'm probably just overlooking something basic, but I've been trying to add fur to this fox model's tail and no matter what I do, the fur remains black. 
I've looked up tutorials, and in all of them, the hair/fur seems to automatically take on the color of the mesh. Am I doing something wrong? The texture has been assigned to the mesh, so that's not the problem. Also, I can't seem to pull up the hair in the node editor, or even select it. Could this be part of the problem? I've tried making the hair into an object, but this changes nothing. I can provide the blend file if that would help. Right now I'm just really confused.
You have a Noise Texture node plugged into the Displacement socket of the Material Output, it messes up the render.
I don't know what you were trying to do with it but anyway you can't directly plug a Noise Texture into the Output, you need at least to put a Vector &gt; Displacement node between the 2.
