I can't change the main color of my meterial

This is my shader

plz help............

 Shader "Exploration/Hair Soft Edge Surface" {
     Properties {
         _MainTex ("Diffuse (RGB) Alpha (A)", 2D) = "white" {}
         _Color ("Main Color", Color) = (1,1,1,1)        
         _SpecularTex ("Specular (R) Gloss (G) Null (B)", 2D) = "gray" {}
         _BumpMap ("Normal (Normal)", 2D) = "bump" {}
         _AnisoDirection ("Anisotropic Direction (RGB) Anisotropic Mask (A)", 2D) = "bump" {}
         _AnisoOffset ("Anisotropic Highlight Offset", Range(-0.5,0.5)) = -0.2
         _Cutoff ("Alpha Cut-Off Threshold", Range(0,1)) = 0.5
         _Fresnel ("Fresnel Value", Float) = 0.028
     }

         Tags { "RenderType" = "TransparentCutout" "Queue" = "Geometry+1"  "RequireOption" = "SoftVegetation"}
