The volume of dust, and the sun rising made the sky a uniform red/pink colour (which was quite sureal when looking at the trees). The nearest I have seen before is in the UK when it has snowed/is snowing at night, and the sodium street lamp light is bouncing off both the ground and the cloud (except in this case we couldn't see the clouds!).
It has mostly cleared now, leaving a film of red dust everywhere - over the car (in looks like it has been offroad!), on the roof, and in the bottom of the pool!
