La Nature se dévoilant devant la Science

The semichromes are
naturally ordered in a
periodic sequence
They contain all hues,
both Newtonean and
non-Newtonean
Ostwald arrived at the concept of “semichromes” by an
intuitive reasoning that can be considered a synthesis of
Goethe’s and Schopenhauer’s primitive notions
It was the first principled construction of
the “color circle” (topological circle) from
the “spectrum” (topological linear segment)
