Google "anomalous reflectance" -- IIRC, morning glories are the worst
culprits; some modern fabric dyes do it too. That was the first thing
I thought of when I saw the subject line, but the complaint seemed to
be more about focus than colour-shift, so I left that out of my reply.
Then again, if the camera picks up IR and the flowers fluouresce in IR,
that would explain "muddled colours" _and_ the softness ... I think?
