Oh, to be on the beach in the tropics now that winter’s here at home.

That’s where I was tonight, at the same beach on Magnetic Island, Queensland where I shot last night’s images of cloud shadows. You can see some of the same effect here, as the few darker clouds cast their dark shadows across the twilight. But in the clearer sky tonight, the classic colours of twilight are more pronounced than they were the previous night. The sunset sky goes from deep yellow near the horizon, through pinkish-purple and into deep blue high in the sky. The “twilight purple” is caused by red sunlight still illuminating the high atmosphere.

We see the same colour effects at temperate latitudes. It’s just a lot more pleasant enjoying a sunset on a warm beach in winter.
