Viola (odorata or tricolor)

[Jorge_Stolfi]

It would be a fundamental logical error to say on the one hand that colours cannot be relied upon in general, but at the same time, when they happen to match, to say that this match is usable evidence

I for one am satisfied that the colors were picked arbitrarily by the Painter, without knowing or caring about the actual colors of the actual plant being depicted.  It is sad to see how many hours and keystrokes have been wasted because of the assumption that the colors carry any useful information.

All the best, --stolfi
