My memory of the Tri Coloured Heron in the West Indies, where I saw it often (sometimes from my office window), was that in the harsh sunlight, it was almost purply blue; very bright, but in the shade was drab, and easily overlooked, so I tend to disagree with the 'garish' comment.
I also based my prior comment on the overall feel of the photograph, and its impact.
I appreciate the need for accuracy in the Opus, and for ID, but I like some artistic photos in the gallery.
