How to make my ChatGUI have the player name have diff properties from the message?

I want to make my pseudo ChatGUI to have the player name different in TextColor3, TextStrokeColor3 and other properties different from the message, but I don't know how to do it! Can someone help me? Here is a script sample of mine (original script has 85 lines of codes)

function NewLabel(parent, msg, player)
	newchatline = Instance.new("TextLabel", parent)
	if player.Name=="PlantChampion" then
		newchatline.Text = "[OWNER] " ..player.Name.. " : " ..msg
		newchatline.TextColor3 = BrickColor.Yellow().Color
		newchatline.TextStrokeColor3 = player.TeamColor.Color
		newchatline.BackgroundColor3 = BrickColor.Green().Color
	else
		newchatline.Text = player.Name.. ": " ..msg
		newchatline.TextColor3 = player.TeamColor.Color
		newchatline.TextStrokeColor3 = player.TeamColor.Color
		newchatline.BackgroundColor3 = Color3.new(27,42,53)
	end
	newchatline.BackgroundTransparency = 0.8
	newchatline.Size = UDim2.new(1,0,0,20)
	newchatline.Position = UDim2.new(0,0,1,-20)
	newchatline.Font = "Legacy"
	newchatline.TextStrokeTransparency = 0
	newchatline.BorderSizePixel = 0
	newchatline.FontSize = "Size18"
	newchatline.TextXAlignment = "Left"
	newchatline.TextYAlignment = "Center"
	newchatline.ClipsDescendants = true
	newchatline.Name = "line1"
end
