How can I add Color property To This Shader

For anyone Need in the future it is really easy.

   Shader "Custom/Jelly" {
          Properties {
              _MainTex ("Base (RGB)", 2D) = "white" {}       
              _TintColor("Color", Color) = (1,1,1,1)
          }
          SubShader {
              Pass {
                  Tags { "RenderType"="Opaque" }
              
                  CGPROGRAM
                  #pragma vertex vert
                  #pragma fragment frag
                  #include "UnityCG.cginc"
       
                  sampler2D _MainTex;
                  float4 _TintColor;
                  struct v2f {
                      float4 pos : SV_POSITION;
                      half2 uv : TEXCOORD0;
                  };
       
                  v2f vert(appdata_base v) {
                      v2f o;
                      v.vertex.x += sign(v.vertex.x) * sin(_Time.w)/50;
                      v.vertex.y += sign(v.vertex.y) * cos(_Time.w)/50;
                      o.pos = UnityObjectToClipPos(v.vertex);
                      o.uv = v.texcoord;
                      return o;
                  }
       
       
                  half4 frag(v2f i) : COLOR {
                      half4 c = tex2D(_MainTex, i.uv)* _TintColor;
                      return c;
                  }
       
                  ENDCG
              }
          } 
          FallBack "Diffuse"
      }
