如何在聊天中将播放器的默认颜色改回来

我一直在学习如何更改玩家的聊天颜色和标签，现在我只想实现将其改回默认

这是代码 (我只包括重要的)

ceValue.Changed:Connect(function()
    local player = game.Players:WaitForChild(ceValue.Value)
    local character = player.Character

    while character do
        if chatService ~= nil then
            local speaker = chatService:GetSpeaker(player.Name)

            repeat wait(1)
                speaker = chatService:GetSpeaker(player.Name)
            until speaker ~= nil

            speaker:SetExtraData("NameColor", ceColor)
            speaker:SetExtraData("ChatColor", ceColor)

            if ceValue.Value == "" then
                for i, v in pairs(game.Players:GetChildren()) do
                    speaker = chatService:GetSpeaker(v.Name)

                    --///这里是我想改变玩家聊天颜色的地方///---
                end

                break
            end

            wait(0.5)
        end
    end
end)
