Default yellow flame on pad

Some of the camera views of the pad show a large yellow flame on one
side (probbaly behind the pad).

What is burning ?

If it were excess hydrogen burning, wouldn't it be a blue flame ?

Yes, it is excess hydrogen and its some ways behind the pad. It is
burned by a kerosene or natural gas flare (someone confirm which?) in
where the hydrogen is mixed to ensure the burning; the venting hydrogen
wouldn't necessarily be at flammable levels on its own. Hence, the flame
is not blue.
