Steve mentioned the purple effect- I believe this is the dreaded Purple Fringing.
Look closely at other parts of the photo you will see it is in many places, look at the trees and the edge of the wall.
Technically it is called Chromatic Aberration (scuse spelling) and (please look it up on the net) it happens with many, possibly all lenses to an extent. I had several Fuji Finepix models which did it in almost every shot taken in sunshine, although great cameras otherwise. It does not occur with any of my Nikon lenses perhaps not a problem with most digital SLR combinations. Dont know what camera Clyde uses. I concluded there was nothing you could do, it is to do with internal lens alignment reacting to light although if you can experiment with the angle you take shots being especiallly watchful if the sun is behind you.
