Decal Shader, Change The Decal Color Separately

I have a decal shader that can have up to 6 different decals, the problem is just that I can only change all the decals to the same color. So I would like to change each decal's color separately.

 Shader "Multiple Decals" {
 Properties {
 _Color ("Main Color", Color) = (1,1,1,1)
 _MainTex ("Base (RGB)", 2D) = "white" {}
 _DecalTex ("Decal (RGBA)", 2D) = "black" {}
 _DecalTex2 ("Decal 2 (RGBA)", 2D) = "black" {}
 _DecalTex3 ("Decal 3 (RGBA)", 2D) = "black" {}
 _DecalTex4 ("Decal 4 (RGBA)", 2D) = "black" {}
 _DecalTex5 ("Decal 5 (RGBA)", 2D) = "black" {}
 _DecalTex6 ("Decal 6 (RGBA)", 2D) = "black" {}
 }
