Different Chat Colors? [closed]

So I've seen people have multi colors in one line of text how would I do that? If you don't understand here is an example Game here, look at the chat I do know how to make a 'chat' show up and color it, I just don't know how to break it up in different colors, I can only do one solid color. (Look at the chat in the game I linked)

game.StarterGui:SetCore("ChatMakeSystemMessage", {
            Text = "Sometext"; -- Required. Has to be a string!
            Color = Color3.new(255/255, 237/255, 96/255); -- Cyan is (0, 255 / 255, 255 / 255). Optional, defaults to white: Color3.new(255 / 255, 255 / 255, 243 / 255)
            Font = Enum.Font.SourceSansBold; -- Optional, defaults to Enum.Font.SourceSansBold
            FontSize = Enum.FontSize.Size18; -- Optional, defaults to Enum.FontSize.Size18
        })
