How do I change the colour and the name of a TextLabel?

Hey Scripters!

So I got this script going on on where I like get overhead gui's. But is there anyway I can change the colours of the TextLabel and the name of the TextLabel, from everything I tried nothing seems to work. This is the script I am currently using:

local gui = game:GetService("ServerStorage"):FindFirstChild("BillboardGui"):Clone()    --Gets the child from the script, which would be the GUI you created

game.Players.PlayerAdded:connect(function(player)
player.CharacterAdded:connect(function(character)
    if player.Name == "maup12345"  then --Checks if you're the owner
    gui.Parent = character.Head --Adds the GUI to your head part
elseif player.Name ~= "maup12345" then
    gui.Parent = character.Head --Adds the GUI to your head part
    end
end)
end)

Kind Regards!

To change the text and colour of a textlabel, you can do this

colour =

TextLabel.BackgroundColor3 = Color3.fromRGB(paste the color3 value u want in here)

text =

TextLabel.Text = (type what u want it to say here)
