Blood-red rainbow

[lethargic_man]

Of a Shabbos afternoon in Edinburgh in 1998, I was walking home towards sunset when I saw an arc of rainbow, thrust almost vertically into the air, faint and almost entirely red: a small amount of yellow permeated its inner edge and a faint hint of green, but no blue or violet whatsoever.

As I watched, and the setting sun reddened further, so did the rainbow, turning completely blood-red before fading away as the sun set. (liv and rysmiel may recall I worked this into a novel I was working on at the time.)

It was an amazing sight, but unfortunately, it was Shabbos and I couldn't photograph it (and even if it hadn't been, most people didn't walk around with camera all the time back then).

It's taken sixteen years for me to see that happen again. My first sight this time of a reddening rainbow was quite a while before sunset, and I foolishly went away and got on with other things, as a result of which when I came back to find this rainbow too entirely red, it was so faint my camera could barely capture it, and I've had to turn the contrast up in the resulting picture so you can see it.
