Bug Default 2DArray is always gray

Declaring a Texture Array texture property, and then NOT assigning seems to always have a default color of "gray", not what I specify.

_Color("Color", Color) = (1,1,1,1)
_MainTex ("Texture2DArray display name", 2DArray) = "white" {}

seems to always sample gray output color.

I suppose it ignores the "white" and assumes you are going to assign a texture? I'm not always going to assign a texture, so I want it to be "white" by default.

 

Unfortunately Unity does only have a grey default texture array.
