Solid color with shadows

Unity Engine
1

Hi all,
i’m approching unity development, so sorry if my question is so noob.
I’m looking for a simple shader that have a solid color as option.
I’m actually using this
Shader"SolidColor" {
Properties { _Color (“Color”, Color) = (1,1,1) }
SubShader { Color [_Color] Pass {} }
}
But this have a little problem… it doesn’t receive shadows. Does anyone have a link to a simple shader ( it will run on mobile platform so lighter is better) like the color one but that receive shadows ?
Many thanks

This might be as lightweight as you get.

Shader "SolidColor" {
    Properties {
        _Color ("Main Color", Color) = (1,1,1,1)
    }
    SubShader {
        Tags {"Queue" = "Geometry" "RenderType" = "Opaque"}

        Pass {
            Tags {"LightMode" = "ForwardBase"}
            CGPROGRAM
                #pragma vertex vert
                #pragma fragment frag
                #pragma multi_compile_fwdbase
                #pragma fragmentoption ARB_precision_hint_fastest
               
                #include "UnityCG.cginc"
                #include "AutoLight.cginc"
               
                struct appdata_pos {
                    float4 vertex : POSITION;
                };

                struct v2f
                {
                    float4    pos            : SV_POSITION;
                    LIGHTING_COORDS    (0,1)
                };

                v2f vert (appdata_pos v)
                {
                    v2f o;
                    o.pos = mul( UNITY_MATRIX_MVP, v.vertex);
                    TRANSFER_VERTEX_TO_FRAGMENT(o);
                    return o;
                }

                fixed4 _Color;
                fixed4 frag(v2f i) : COLOR
                {
                    return _Color * LIGHT_ATTENUATION(i);
                }
            ENDCG
        }
    }
    FallBack "VertexLit"    // Use VertexLit's shadow caster/reciever passes.
}

Great! thank you very much.
