I snapped this quick before it left and can't help noticing the change of color in the sky either side of the rainbow... I've never noticed it before...

that's a 'hot' shot Lynn!!! The division by the rainbow between the different sky-types is really cool, the trees also have a very appealing effect on the photo
thanks for sharing!

Lynn, What yoiu photographed has been observed and recorded since the Greeks. The area outside a primary rainbow, and inside a secondary bow is called Alexander's dark band - I do not see the secondary rainbow in your image but it should be about 8 degrees further outside the primary rainbow.
In Lynch and Livingston's "Color and Light in Nature" there are numerous images of rainbows and they all demonstrate how much darker the sky is outside the rainbow than inside.
Galen Rowell favored M.G.J.Minnaert's "Light and Color in the Outdoors" for scientific explanations of light and weather in the outdoors. It was originally in French and is not light reading, but gives very thorough explanations of rainbows and fogbows.
I picked up the Minnaert reference from Galen Rowell's "Inner Game of Outdoor Photography" but Lynch and Livingston is a little easier to read and has lovely color photographs to illustrate the effects of light and weather. I found both on Amazon easily.

Andy, Sometimes I talk too much and come across like a school teacher. I know I do , I just can't help it sometimes. But I like to share some secrets I have learned along the way.
Galen Rowell's book "Inner Game of Outdoor Photography" really deserves reading and introspection. He describes the thinking processes and inspiration for his images. For him, shooting the images, at times, was almost a matter of recording what he had already planned in his head.
His discussion does not center on equipment, but on visualization and inspiration. There are whole articles in this book that I need to have a Hi-Liter to underline as I read, so that I can return again and again to the real stuff. The pictures are great also. His loss was a great loss to all who love the outdoors.
There is a picture on page 201 of his book of a climber silhoutted on a spire and he is outlined by brilliant sunlight like he had been traced by a brilliant magic marker!! Rowell said of this image "I had scouted the site the previous day and knew the conditions were optimal for this effect." He shot 35mm film also - not digital. He read Minnaert's book and understood it well.

I hadn't noticed sky difference thing before. Now with the technical explanation I feel like I have broadened my knowledge. (I just need to purchace some more memory so stuff stops falling out each time I cram more stuff in.)
