Ending A Loop but then restarting at while true?

local seconds = game:GetService("ReplicatedStorage").CrashGoing.Seconds

function changingColor()
    while true do
        wait()
    if running.Value == true then
            wait(0.1)
            if number2.Value == 2 then
                if seconds.Value <=1 then
                    return end
                gui.TextColor3 = Color3.new(0, 0.333333, 1)
            end
            if number2.Value == 4 then

            if number2.Value == 6 then
                if seconds.Value <=1 then

                gui.TextColor3 = Color3.new(1, 0, 1)
            end
            if number2.Value == 10 then
                if seconds.Value <=1 then
                    return end
                gui.TextColor3 = Color3.new(1, 0.839216, 0.0235294)
            end
        end

changingColor()

This works until the if seconds.Value comes along. Then the script just ends. I tried just using returns and what not however not worked. I want to make it so the script stops but then goes back to the while true do.
