I remember that in my youth, 1950s, the colour of the moon seen from the UK
was blue, due to forest fires in North America. AFAIK, this has not happened
again in my lifetime.
Cheers, Alastair.

1950
26th September): 'BLUE MOON' EVENT.
1. Smoke particles from large-scale forest fires in Alberta, Canada were
blown across to NW Europe on strong upper-level winds and led to the
widespread viewing of a very rare 'blue moon' event. The base of the
pollutant cloud was around 12000 ft and the top circa 20000 to 25000 ft.
In addition, the sun was coloured when it appeared through gaps in the
cloud. Aircraft traversing the cloud were covered by an oily substance
believed to be a resinous distillate from the burning wood.
