Diffuse * _Color turns wrong on ios ?

Unity Engine

I’ve taken all _Color fields out of my shaders because I rarely need to multiply my Diffuse by a color,

but somtimes it turns likes bellow on ios decive :

Additional I am using Unity4.2.2 Even Diffuse shader may turns wrong

Many of the built-in Unity shaders require a _Color property to be present.

If you’re using any of them as a fallback (including the shadow caster/receiver passes) then you’ll need to keep the _Color property in there for them to use. Even if it’s not used in your shader.

Thanks for reply.
Here is my code :

It could be wrong sometimes when load a level, but after remove _Color,just like Mobile/Diffuse, it goes right…
But I really need a _Color property

try this

Shader "Mobile/ColoredDiffuse" 
{
	Properties 
	{
		_Color ("Main Color", Color) = (1,1,1,1)
		_MainTex ("Base (RGB)", 2D) = "white" {}
	}
	SubShader 
	{
		Tags { "RenderType"="Opaque" }
		LOD 150

		CGPROGRAM
		#pragma surface surf Lambert exclude_path:prepass noforwardadd

		sampler2D _MainTex;
		fixed4 _Color;

		struct Input 
		{
			half2 uv_MainTex;
		};

		void surf (Input IN, inout SurfaceOutput o)  
		{
			fixed4 c = tex2D(_MainTex, IN.uv_MainTex);
			o.Albedo = c.rgb * _Color.rgb;
			o.Alpha = c.a;
		}
	 ENDCG
	}

	 Fallback "Mobile/VertexLit"

 }

You have a typo there;

should be;
uniform fixed4 _Color;
