I was quoting from the article, which, admittedly, isn’t straight from the horses mouth. If there’s a discrepancy, one of them is wrong (I think I know which).
> While there’s no display, the illuminated ring behind the grip does provide a visual indicator of what the iron is doing: solid blue means it has power but the heating element is off, a pulsing blue indicates the iron is heating, and orange means it has reached the desired temperature. If you flick the heater switch off, the ring pulses purple until it cools back off and returns to blue.

What he says matches their documentation as well:
>Blue LED: The iron is below 40° C / 100° F and is safe to touch.
>Purple LED: The iron is actively heating up or cooling down. Iron tip is not safe to touch.
>Orange LED: The iron has reached the user-set temperature and is ready for soldering. Iron tip is not safe to touch.
