Some of the fires in those videos have a strange purplish or blue glow at their edges. Is that flame burning outside the visible spectrum and can it be seen with the naked eye? Example: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;Fym6X-JvEOs?t=1m8s" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;Fym6X-JvEOs?t=1m8s</a> Or just an artifact of the recording technology?<p>If it&#x27;s burning outside the visible spectrum, and the same part isn&#x27;t also emitting visible light too, then that&#x27;s really scary - it would mean that every time you see a fire like that, it&#x27;s actually considerably larger than it seems.<p>I am curious whether you could see hydrogen burning on a camera like these dashcams.<p>Edit: This is absolutely <i>crazy</i>. What is going on in this video? <a href="https:&#x2F;&#x2F;youtu.be&#x2F;Fym6X-JvEOs?t=1m59s" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;Fym6X-JvEOs?t=1m59s</a>
