Replicating orginial green dash pad

[TotalChevy1]

I'm hoping someone else has had this challenge. I'm in the process of redoing the interior and I'm going with a completely stock interior. The problem I'm having is I've bought a couple different dash pads from vendors and they are not the same color as the factor pad. The factor pad has more of a olive tint and is lighter. Has anyone been able to location a pad that is the same color as factor or has been able to duplicate it? If someone has been able to duplicate if you could give me the specifics......I thought the pad would be the easiest part to replace.....

Thanks,
