Roblox scripting dialog change color script?

How can I change a dialog color in scripting in roblox studio because it works on my client/local (Also known as running the game through roblox studio) but not through the game it self.

local Core = script.Parent
local Charles = Core.Charles
local Fern = Core.Fernando
local Step = Core.Stephanie
local Wendy = Core.Wendy

function onStart()
Wendy.Head.WendyTalk.InUse = true
end

Step.Head.StephanieTalk.DialogChoiceSelected:connect(function(player,choice)
Step.Head.StephanieTalk.Tone = "Enemy"
if choice.Name == "ContinueLoser" then
    Wendy.Head.WendyTalk.InUse = false
elseif choice.Name == "FightBack" then
    player.Character.Humanoid.Health =   player.Character.Humanoid.Health - 10
end
end)

Wendy.Head.WendyTalk.DialogChoiceSelected:connect(function(player,choice)
Wendy.Head.WendyTalk.Tone = "Enemy"
end)

Charles.Head.CharlesTalk.DialogChoiceSelected:connect(function(player,choice)
Charles.Head.CharlesTalk.Tone = "Friendly"
end)

Fern.Head.FernandoTalk.DialogChoiceSelected:connect(function(player,choice)
if choice.Name == "Agree" then
    Fern.Head.FernandoTalk.Tone = "Friendly"
elseif choice.Name == "Disagree" then
    Fern.Head.FernandoTalk.Tone = "Enemy"
end
end)

I also know this is a correct code as well, just wanted to post it here just in case because I've tried localscript and a script and it only works on the test play in the Roblox studio program so I mainly need help with suggestions and ideas of how to make it work on Roblox itself than just the Roblox studio program because I've tried searching the web for help but the only help was how to create dialogs when ever I already know how.

Update I do not need help on this anymore, I'll leave my answer below.
