I've been trying to make this one for a while any ideas on how to create it. This was solved by DaRealAKASGaming. Paste this script into a local script in startergui!
sm = BrickColor.new ("New Yeller")
game.StarterGui:SetCore("ChatMakeSystemMessage", {
Text = "Testing message";
Font = Enum.Font.ArialBold;
Colour = sm.Color;
FontSize = Enum.FontSize.Size96;
})
