Function won't work on server startup?

So I have this script that runs when a player enters a game:

    repeat wait() until Player.Character
    wait(.5)
    getDefaultSkin(Player)

the code for the Default Skin function is:

function getDefaultSkin(Player)
    wait(.1)
    local Characters = Player.Character or Player.CharacterAdded:Wait()
    if game:GetService("Players"):FindFirstChild(Player.Name) and           Player.Character.Humanoid.RigType == Enum.HumanoidRigType.R15 and      Player.Character.Humanoid.Health > 0 then        
        Player:ClearCharacterAppearance()
        print("Destroyed")
    else
        print("Player Not Found")
    end
    wait(.1)
    Player.Character.UpperTorso.Color = Color3.fromRGB(58, 125, 21)
    Player.Character.LowerTorso.Color = Color3.fromRGB(58, 125, 21)
    Player.Character.LeftUpperLeg.Color = Color3.fromRGB(86, 66, 54)
    Player.Character.LeftLowerLeg.Color = Color3.fromRGB(86, 66, 54)
    Player.Character.RightUpperLeg.Color = Color3.fromRGB(86, 66, 54)
    Player.Character.RightLowerLeg.Color = Color3.fromRGB(86, 66, 54)
end

The problem is that it clears the player's appearance, but it doesn't change the colors of the player. This only happens when you are the first one in the server so the problem is probably something to do with the server startup, but I don't know how to change my function so that this works from the start
