Blue within blue

For Katie, who has taken the plunge.

A feeble attempt to demonstrate the colours changing depending on the viewing angle. (Seven thirty on a dark December morning has nothing on the bright light of a sunny summer's day.)

(With a bit of luck and a following wind, these pictures should be clickable so that you can see the wing - and the silver mount, which I really should have polished before I started messing around with the camera - in greater detail.)
