The reason for the red helmets was the uniform rules at the time. Players had to wear the same helmet all season unless it was damaged. They couldn't use white ones for just that game.  They had to put the big white standing Buffalo over their normal helmets.

I don't think this was the rule then. Several teams that year wore different colored helmets. Denver switched from blue to orange in this particular game.
